Mike,
The spring also serves to locate the top of the
suspension uprights fore-aft. That's why there are
links on the bottom of the uprights, but not the top.
The spring sits in a slot machined into the top of the
diff housing. This transfers the forces from the
spring into the diff, and then to the chassis.
A simple flat spacer will not keep the spring from
'walking' under stress (heavy braking, cornering,
acceleration, etc. i.e. the times you least want it to
happen).
You can address this problem in several ways:
1) Use sleeves on the outer four stud/bolts, thick
enough to wedge the spring between them.
2) Use shims or spacers ground to fit very tightly
between the outer stud/bolts and the spring, tap them
in place with a hammer.
3) Weld onto the spacer 2 steel strips on the top to
fit the spring, and one onto the bottom to fit the
slot in the diff.
4) Design, fabricate, and install the top suspension
links (called Kastner links BTW) to locate the top
suspension uprights.
5) Have a spring shop de-arch the unit 2" for maybe
$40-50.
Just thought you'd like to know.
