When I put the 347/T5 in my 67 GT350 the front end raised up about 1" (I guess because the engine/tranny was lighter). Then I added pinion shims in the rear which lowered it about 1/2". I know that the Shelbys original had a "nose up" attitude but this is ridiculous.

I want to lower the front end but I DON'T want to cut the coils on the original springs. I also want to avoid putting in a spring with a harsh spring rate (like 620#). I like the springs that are in there so if I could find a set of 1" lowering springs with the same spring rate I would be happy.

IIRC the coil springs in 67 GT350s had a different spring rate from regular GTs (I could be wrong about this).

Does anybody know what the spring rate was?
