So I'm trying to install the rebound straps and rear shocks. I have the axle sitting on jack stands. the rebound strap Moss sold me, 267-565, for a 69 mgb, wont quite reach. also, do i tighten the link bolts to the freshly rebuilt rear shock, or leave them loose and tighten them after the wheels are on with the car on the ground?

Have you recently replaced the springs also? New springs often need extra weight, in the trunk, to fasten the straps. You can tighten the shock bolts now, however. RAY

Also depends on how you have it jacked up. If you have the suspension hanging with jack stands under the body then no straps will be long enough, put a jack under the diff and load the suspension some and the straps should fit. With the Moss straps you cannot hang the suspension from them though, they won't take the weight and will snap.

no, the rear axle is sitting on the jack stands. the weight of the body isn't enough, especially with the shocks hooked up. Guess I'll unhook the shocks, put weight in the body,then hopefully attach the straps, followed by the shocks.

Too late now but should you break them next time get Strapping Lads' - I thought everyone (other than those being an absolute purist) got those rather than the rubber rubbish.



Convertible: CKD 11/66 first registered 8/5/67. Owned since 3/77. 90% original sheet metal. 18GB +40 balanced with almost all new internals. Peter Burgess big valve fast road head. Piper 285. Fidanza FW. Basil's followers and pushrods. TR7clutch. TT exhaust. ARP everywhere. 123 ign. Needham 4synchro c/r box.. Stock rebuilt/replaced suspension. Superpro bushes. New brakes all round including all pipes in SS flex. Interior redone. CAMS approved roll bar and side bars. Lots more. Hybrid of o/e and show/fast road car. Not for sale - it's my toy!

GT: UK car built/sold December '78. Stripped back to bare shell (with extensive bodywork to come). Powered by 'worked' Rover 5 litre V8 (ex TVR Chimera) with efi. T5 box. FC IFS. CCE rear attached to Salisbury axle with Quaife. And a whole lot more to yet to come. Stealth is the word.

There is no need to disconnect the shocks because they are just dampers and do not "push" the axle downward. I'd suggest you either throw some weight into the truck (sand bags, tool boxes, or whatever) and/or jack up one side of the axle to get more weight on that side (and, of course raise the jack stand on that side for safety).

I did see a post within the last week where the author said the straps they got from Moss were shorter than some others that they subsequently purchased elsewhere (try a search). As I recall, the poster said that with the axle hanging by the shocks, the distance between the centers of the strap mounting points was 10.5", his Moss straps were 8.0" and were expected to stretch 0.5" under the weight of the axle. So, by his reconing, their was 2" of unuseable shock travel. So he got some 9" straps to reduce this to only 1" of unused travel (you do need some in order for the straps to protect the shocks from bottoming out).

Well, I managed to get them installed by doing as suggested and using weight to bring them to their mounting point, but they feel a bit taunt. I thought there should be more play?

Seems to me that having the rebound straps in tension when the car is sitting on the ground is just wrong. If nothing else, the life of the straps will be diminished.
