Does anyone know what the OEM part number should be and or where to source a non-chineasium repro with the correct spring rate?
Was there just one PN for the 400s regardless of engine options???

I do see Inline Tube, Fusick and YO offer a will-fit.

I'm doing some research on this... its PN and engineered spring rating. (Please excuse my NCRS tendencies)

Steve , the GM AC part number is CV679C and I'm still waiting to hear from you.

The original Oldsmobile P/N is 6421972. I don't know how this crosses to AC Delco P/Ns, unfortunately.

69HO43

Both GM and Delco part numbers usually, but not always, stamped on the end of the GM/ACDelco box. Like this.

Well, that would be it.

Awesome guys thanks. I did some more research this AM and yes thats the right number. Fusick has it.
