I looked hard again and think they are actually "HQ". GM# 3955724.  Having a tough time finding info on this # 3955724 with "HQ" tags.  Would love to match the spring rate and ride height.

"HQ"'s were used on ZL-1's. I actually have a set that I took off the front of my car during the resto.

I believe the "HQ" was also used on SS396 with 325hp or 350hp.  I wish someone knew of a very close replacement.  Moog 638 and 6312 are not really close as far as the spring rates go.  I read the "HQ" springs are 1830 lbs (LOAD) and 345 lbs/inch (RATE).

Possibly they were used there as well but who knows.

I have a single fuel line so I doubt my car was one of those. Too early for ZL-1, not on the list, DG3 on the rear seat bulkhead.  Original chabered exhaust car. Hard to say what it was originally with any certainty. The possibilities are mind boggling. I had to just believe the DG-3 crayon mark and run with it. I will keep the car and the springs indefinately just in case better info comes along some day.
