[Fot] Lever shock mounts

Bolts are usually for tightening in tension.  But the bolts for the rear 
lever shocks are different in that when the lever arm moves up or down 
during a bump, the shock body wants to rotate.  If the bolts are not tight 
(in tension) then the body of the shock will rotate and the holes in the 
support will become oval.  This could lead to weakening the support welded 
to the frame.

I found it difficult to get a socket on the hex head because there is so 
little clearance beween the socket and the recessed part of the casting for 
the shock body.

To keep mine tight, I made 4 tubes 1-1/4" long and mounted the shocks with 
bolts 1-1/4" longer than the original bolts.  This puts the hex head further 
away from the shock body and because the hex head is now away from the 
casting, it allows me to get a big socket on the head to make sure the bolts 
are all really tight.
