rear leaf spring

so it looks like buying you have a choice between 2 1/4 and 2 1/2 inch width springs...  so I measure at the mount area and it seem to be right between, like 2 3/8

which do I get?   1978 standard

You prolly need the 2 1/4" spring. Re-measure it closer to the diff/center. The ends of the springs are flared where they attach to the trailing arm bolts. Thumbs Up

The Pace car which has the original on it appears to measure 2 1/4" and 6 leafs. 
Also has the FE7 Gymkhana Suspension. I don't know if that would make any difference.

FE7/Gymkahana springs were 6 leaf. Regular suspensions had 9 leafs.
