Just wanted thank you for this post - I have ordered a pair of 21/979/1 couplings from Robush (They didn't know which couplings in their catalogue fit the GT6 MK 2) so I relied on the information you shared here to get the right ones. 

At < £200 for a pair of genuine Metalastik couplings, I question the sense in CV conversions or Chinese copies for anyone who owns these cars

No problem. Happy to help. Just to say the rebuilt hubs and rotoflexes are all good.  In fact, as well as a bit of running in mileage, I did the 2000 non stop Round Britain Reliability Run shortly after and everything performed faultlessly.  Having worked on the rear end of the Gt6 3 times now  (swapping a second hand diff, rebuilding hubs and rotoflexes and, just recently, fitting a recon 3.63  diff to replace the first one I fitted, ) it’s got easier each time.  The last diff change was pretty painless now I know what I’m doing and I did it on my own.  Just need a spring lifter and a couple of jacks properly placed. Shimming the hub is the trickiest part of working on these but you have to do that with a CV conversion.  One triumph specialist I know swears that rotoflexes help to preserve the slightly under spec triumph diff.  Don’t know if that’s borne out in reality but given how rotoflexes work it seems to make sense.

Just thought I'd add my experiences to this.  I've had to replace the radius arm brackets on my GT6 which necessitated removing the driveshaft and vertical link from the car so decided to go the whole hog and replace the slightly cracked donuts and rebush everything plus new timken bearings (rimmers).  Decided to stay original so sourced some proper metalastik units.  Demon Tweeks have them at £167.20 each (incl VAT)!!  However, looked online and a firm called Robush Ltd https://www.robush.com/products/rotoflex-coupling/ do them.  They were very helpful   - cost £89.25 plus vat each (£107.10 incl VAT) plus £12.50 for next day delivery (in stock whereas Demon Tweeks say will get stock in within 7 days).  just like to let people know if they are looking.  You need to call or email as they don't sell online.  You need to quote the part number which is 21/979/1 (there is a link to the original catalogue.  Saves you £120 over the Demon Tweeks items (and probably only costs you £100 over the repro rubbish!)

Checked the price with Robush today and the price is now £126 each plus postage . That’s inflation or ripoff

I asked about the Metalastik donuts pricing and Robush said the price had gone up but they give Motor Clubs discounts . I have passed all the info on to Angie , hopefully the club might be able to purchase some .

Is that £126 plus Vat or inclusive ?

Inclusive

So about 17% increase but still a lot less than Demon Tweeks but a biggish hike.  Prices are increasing for all sorts of things significantly.  Hard to keep up.

That's roughly what I paid Robush last week. £20 for next delivery.
