The build sheet on my T/A shows rear spring last 3 digits of 048. I could not find any spring that ends in 048 in the master parts book. Also my build sheet shows the rear shocks last 2 digits of 54 which I think might be the standard 340 spring (3400854). I thought these car got the C body rear shocks with the longer travel.

Rear spring numbers are 3400048 - it is in each bottom leaf.

54 shocks were used on 340 4-bbl Challengers also. I have not heard of them being used on C-bodies?

Cuda 340 also used the 54.

trans am cars used the lower shock brackets from a b-body to help compensate for the raised rear

The spring mounts came up back in 2003, so I looked under several AARs & T/As that year. There were two different spring mounts used in real life, not sure why.

There is also a handwritten document from someone inside the program that says

Rear Spring 340048 with "C" body spring plates

I will look for other references to it as time allows, thanks for the book Frank!

The use of the b-body spring plate was to allow the 054 shocks to still work. Chrysler did this to compensate for the different arch in the springs and allow the 054 shocks to still work.

What is the correct part number for the front shocks?
