Jonathane,
Been there, done that!
First- you need a later model spring.
Second- (2) new half shafts. The later model Spits are a total
of 1" wider.
Third- Are you going to press those things yourself?
(Look up old thread $$$)
Fourth- You will most likely run into clearance problems.
The spring sits a little lower and the axles
stand
a little wider. Result-tires hit fenders.
If your willing to go through all that work, than you should replace
your shocks, diff mounts, bushings and u-joints as well. This ='s $$$
It is, however, the route I took on my '64 restoration and I didn't
notice much of a difference in handeling. A bit less roll but I think
that an anti roll bar would have given about the same increase in
performance. If I had to do it over again, I would have replaced the
shocks with a set of Konis, replaced the mounts, installed urathane
bushings, new u-joints and an Addco 5/8" anti roll bar. Good tires can
also make a big difference. Oh yea- If you need to replace your leaf
spring, I would suggest TRF over Vic Brit. Good luck!
PL '64 Spitfire
