Looking to replace my rear coil springs. I'd like to use Moog, but cannot find an accurate part number. I even called them and they just told me they stopped making springs for my car and couldn't tell me a part number from when they did make them. I tried searching this forum, but there's like 3 or 4 part numbers thrown around. Ideally, I'd like to have numbers for both stock ride height and to raise the rear a bit, just to have options but I am leaning toward keeping the stock ride height.

 

I realize its the opposite of what you want, but I have a full set of Hotchkiss 2" lowering springs that are new. They were installed but never driven. I'd make a deal for all four.

 

You can use the same part number for a Cutlass, Buick Skylark, Pontiac Lemans, or Chevelle.

 

Look up Mevotech - they make springs aligned with Moog part#s and specs - if you know your Moog part# you can cross-reference it to the Mevotech springs, which can be sourced from them directly or via several other vendors (I bought their p/n SMS6435 rear springs thru Summit)

Stock height moog springs are part number 5231

 

I have 7501 or 04s, i think. I thought the original was a 6401.

 

Thanks guys! So... A friend of mine has a 67 Cutlass and said he had no trouble getting springs off of a Moog website. I went on there and put my car in but with 67 instead of 66 and sure enough the part number came right up. I think for whatever reason the 66 GM cars are just gone from their database. Anyway... Part number 5385 is listed as being for the 1967 Cutlass/F-85/442. 5385 was one of the numbers mentioned in other threads here for the 66 cars, so I'm going to assume it's correct for 66 cars as well. I'm not doing a concourse restoration so it doesn't matter to me--just want the car to sit at close to original stance, so 5385 should work at least for me.

 

66 and 67 use different rear springs. They don't interchange.

 

Well… Sh*t.
