If a 69 Z/28 came with the optional 5 leaf rear springs would they still have the Z/28 yellow (BM) code tag or would they have the BB 5 leaf code tag which I believe is a yellow (BK) code tag? Thanks, Sam

Any spring would have the tag that matches that spring part #.

Thanks Kurt. I assume it gets the (BK) tag. Sam

I should add I've never seen a 69 Z with 5 leafs. There was no spring option for Z's.
Not to say they couldn't exist, but the service spring tables clearly show only one part for Z's, BM.

This is a good question for Jerry. :)

Kurt, what was the difference between the three front springs for Z/28? The rate, free length?

It must be rate. The AMA submission shows the same design height (height at design load) for standard V-8 and Z/28 springs, but the Z/28 springs have a shorter overall (unwound) coil length and larger bar diameter. Free length of a coil spring is essentially meaningless - coil springs are rated at their design load, not at free length.
