GT-6 MKIII Owner Posted July 22, 2019 Report Share Posted July 22, 2019 The unrusted 1973 bodyshell (from Oklahoma-no road salt!) does not have the mounts for rear shocks in the inner fender wells. This is because in 1973 Triumph reverted to swing-arm suspension. I have been unable to find all 4 parts required (714655 and 714656 are available but 821154 and 821155 are NLS). I have read that TSCC sells or used to sell a kit that eliminates the need for these. Is this still available? Can't seem to find it. Joe Curry at Spitlist used to make a bracket to do this but no longer makes it. I have also read that Moss Motors makes such a kit but again I can't find it. Any suggestions? I am new here but I do love my GT-6 and want to restore it. Until I took it off the road 20 years ago I drove it daily and worked on it even more often.

NonMember Posted July 23, 2019 Report Share Posted July 23, 2019 I'm pretty sure the conversion kit is still available from all the usual suspects. Here's the Rimmers link as it was easy to find - others may be cheaper. Link to comment Share on other sites More sharing options...

GT-6 MKIII Owner Posted July 23, 2019 Author Report Share Posted July 23, 2019 Thanks, guys, just ordered it (without shocks) from Rimmer. What a relief! Now I don't have to find somebody with a parts car and pay them to drill out/unweld the 50 year old brackets and weld them on to my bodyshell.

Qu1ckn1ck Posted July 23, 2019 Report Share Posted July 23, 2019 I hope that your shocks fit. When I fitted the brackets to my early Mk 3 my existing shocks were too long so I had to buy shorter shocks to fit. Nick Link to comment Share on other sites More sharing options...
Paul H Posted July 23, 2019 Report Share Posted July 23, 2019 Dont forget the brackets are handed and the stepped bolts only go in one way ( assuming they are the same as the Club Shop ) Paul Link to comment Share on other sites More sharing options...

The kit is clearly marked as a conversion kit that fits shorter (and far more common) shocks than the absurdly long ones originally used on Rotoflex cars. The later, swing spring cars used shocks that will probably work fine, even if the TSSC advertising claims would imply otherwise. 1 Link to comment Share on other sites More sharing options...
GT-6 MKIII Owner Posted July 24, 2019 Author Report Share Posted July 24, 2019 Very good to know. Thanks to you both. What I read in some of the Forum threads fits in with this also. Anyway, the brackets are bought and the shocks are way further down the road. Link to comment Share on other sites More sharing options...

A local GT6 owner (one of the very best out there) had the club kit, and despite a newish STD spring at the correct ride height, the shocks were bottoming out. The club sorted it via Gaz, but I would be wary about using spitfire shocks. On the other hand, I don't understand why the brackets do not get a slight redesign so STD spit shocks would work...

GFL Posted July 24, 2019 Report Share Posted July 24, 2019 The open and closed lengths of the Shocks are important when using the Chassis mount brackets with the Roto-flex type Suspension. I used Koni 80-1717 Adjustable Shocks on my Vitesse which have an open length of 296mm Eye to Eye and a closed length of 218mm. They worked well and I never experienced any bottoming out, although modifications are needed to to the top and bottom bushes, as they are actually designed for the Front of an Early Mini but certainly work well on the Rear of a Vitesse.
