Looks like it just needs a machined spacer either end as Stan said

I guess the good thing about this design is that it will be easier to take off, getting the stock shock off is a challenge sometimes.

You have space to cut through the bush if it’s rust-welded itself to the bolt.

I'm a great believer in the stuff and even use it in places where I shouldn't (head bolts, suspension nuts), I know its good for a few years but I wonder how long it lasts? Most of us change shocks when they have eventually given up to the extent it can't be ignored any longer.

Reading Stans sketch i wouldn't want the sleeve as the only point of contact, looks like a potential weak point to me.

Even on the originals the bush takes all the contact load, if the rubber did touch the sides it would gradually wear away with movement. The bolt has a large torque (Not checked the book but M14 HT = 100+ ft-lbs range), the clamping force is enormous.

+1

Just fit the shocks as they are. Mines lasted 9yrs with some spirited use albeit on steel arms v ally ones. Remember the weight of the car is mostly on the torsion bars and NOT the shock. Take the shock out and the car still stands up! Just has no bounce control
