Pete Lewis Posted November 21, 2019 Report Share Posted November 21, 2019 a thought on RolyB earlier ,, if swapping to a swinger you might have to fit the longer drive shafts think this change came on the 1500 not the mkIV but its just a thought. spring lengths must change ive not checked Pete Link to comment Share on other sites More sharing options...
Nick Jones Posted November 28, 2019 Report Share Posted November 28, 2019 You don’t need the longer shafts. The swing spring was introduced with the launch of the MkIV Spit, before the long shafts. The spring length doesn’t change anyway, only the angle of the vertical links. Nick Link to comment Share on other sites More sharing options...
s99sdp Posted January 10, 2020 Report Share Posted January 10, 2020 Happy New Year everyone. As an update to this conversation. My new spring from GB Springs finally turned up yesterday. I haven't seen it yet as I had it delivered direct to my fathers as that's where the car is. I know it's important not to go off topic on these threads but this is clearly linked, can anyone suggest a non bank breaking bush kit for the spring and stabilising arm? It makes sense I replace these while the spring is off but some of the ones I've seen are crazy prices. Any suggestions, links to items and advice will as always be greatly appreciated.

s99sdp Posted January 10, 2020 Report Share Posted January 10, 2020 Thanks Pete, as I'm the most heavy duty pen pusher your ever going to come across and not mechanical in any way shape or form, I'm going to ask the question you didn't want me to. Which of the items on the page for the rear will I need, all of them? SP Link to comment Share on other sites More sharing options...
Colin Lindsay Posted January 10, 2020 Report Share Posted January 10, 2020 Page three has the rear leaf spring eye bushes/ kit, bottom left, and one row above that to the right is the rectangular pad for inside the swing-spring mounting box. Stabilising arm I'm assuming that's what I call the rear radius arm, the kit is the one directly above the rectangular pad. Link to comment Share on other sites More sharing options...

I can just about operate a computer...... And you guys are the absolute brains of the outfit. Thanks for your help! I'll get this ordered and plan for the swap out of the spring.

Waynebaby Posted January 10, 2020 Report Share Posted January 10, 2020 Regarding bushes, the spring from GB will come with new bushes fitted to the eyes at either end. These will only come out with a struggle, so you may want to stick with the ones that it comes with - I left mine in (but changed all the other bushes that you propose doing) and three years on the GB fitted bushes are as good as new. Removing the original bushes from the radius arms can also be problematic. The front bushes are especially hard to remove by mechanical means in my experience and over zealous use of the vice can make the eyes non circular (don't ask how I know!) I've found the easiest way to get the old rubber bushes out of the radius arms is to take them into the fresh air and burn them out with a blow torch. Stand up-wind because they'll produce horrible black smoke and then re-paint the arms before you fix in the Superflex bushes Wayne . Link to comment Share on other sites More sharing options...
s99sdp Posted January 11, 2020 Report Share Posted January 11, 2020 Thanks Wayne. It did indeed come with its own bushes so I'll just order the pad and radius arm bushes which makes it a lot cheaper. I appreciate the heads up with getting the bushes out too. I wont even try another way, just go straight for the burn. Cheers SP Link to comment Share on other sites More sharing options...
Waynebaby Posted January 11, 2020 Report Share Posted January 11, 2020 SP I'm happy to pass on what I've learned from my mistakes! The original rubber bushes at the front end of the radius arms are made of two concentric steel cylinders with rubber bonded between the two - the whole assembly is an interference fit in the eye and was pressed in hydraulically. This means that when the rubber is burned away the larger steel cylinder will remain in the eye, and this has to be removed before the Superflex bushes can be fitted. If you are fortunate this can be drifted out with a stout screwdriver and a hammer. If this doesn't work, then the steel cylinder of the old bush needs to be cut with a hacksaw (be careful or you'll damage the eye - once again, don't ask me how I know!) after which brute force and ignorance will free the remnants of the bush from the eye. When re-painting the radius arms, don't paint the inside of the eyes. The new bushes will push in with the aid of a vice. Wayne Link to comment Share on other sites More sharing options...
s99sdp Posted June 27, 2020 Report Share Posted June 27, 2020 ok, at long last due to lockdown and medical issues on my part my cousin and I attempted to replace the rear spring for the new one I bought from GB SPRINGS. We have a problem. Keep in mind I'm stupid and not a mechanic. The plate that goes over the spring wont locate properly because there's a knuckle on the spring which would mean lopsided pressure on the spring plate. You'll see from the picture that we cant get enough thread through the nuts and even if we could, it still doesn't seem right. This is the spring I was sold by GB SPRINGS, I made it clear it was a 1970 Mk3 and even gave the number plate so I'm confident they send me the correct one. He did say its a higher rated spring than the originals but should there be some fitting pack to allow for that knuckle in the middle that isn't there on the old spring? I hope this meandering comment makes sense. I'm calling on the holy wise men of the TSSC community do dig me out of yet another hole this serious pen pusher has found himself in. Thanks in advance for any help you can give SP Link to comment Share on other sites More sharing options...

Pete Lewis Posted June 27, 2020 Report Share Posted June 27, 2020 from your photo thats a mk4 > swing spring has a (4 stud and box ) you are trying to fit in a fixed spring (6 stud ) diff with a 6 hole top plate it wont work the clamp you see i reckon is just for transporting, but what you have is all wrong unless your car had a 4 stud swinger fitted and things like shaft lengths come into question i guess your orig spring does not have the kink for the swinger box Pete Link to comment Share on other sites More sharing options...

Badwolf Posted June 27, 2020 Report Share Posted June 27, 2020 It might be a backward step, but you may be better taking the spring and fittings out and posting a photo so we xan see what you have been sent. Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 27, 2020 Report Share Posted June 27, 2020 yes a very wrong spring,, depends just what you ordered , to fit that you need a a swing box a top plastic block, and a bottom clamp plate as used on MkIV and 1500 https://www.canleyclassics.com/?catalogue=triumph-spitfire-mkiv/1500&diagram=triumph-spitfire-mkiv/1500-rear-suspension-road-spring Link to comment Share on other sites More sharing options...
