1955 Spindle Support Numbers

[Michael S.]

Does anyone have a quick reference available that gives the numbers cast on the left and right spindle supports for a '55?
I also need to know if the numbers ever changed from '53 to '62.
Does 3687651 and 3687652 ring a bell?
Thanks,
Mike

John,
Thanks very much. That's exactly what I needed. The piece I came across must be a passenger car front cross member.

I believe that the spindles were GM #3706021 and 3706022 for 1953 to sometime in the 1956 model year. Thereafter, to the end of 1962 production, they were GM #3733449 and 3733450.

The 3733449 and 3733450 replaced the 3706021 and 3706022 for 1953-56 SERVICE in July, 1956.

joe, wish i had your books! my april 55 parts catalog never listed that number. is the 57 parts catalog the first catalog that includes the corvettes with the car and trucks?

The 1956 is the first catalog that that combined Corvette with passenger car and light truck. Prior to that time, the Corvette parts catalog was a stand-alone catalog. In October, 1969 it went back to being a stand-alone catalog.

By the way, I'm not too "tuned in" to C1 stuff. However, when I saw the 3733449 and 3733450 part numbers you posted, I thought they looked too "1957-ish" to have been around as early as 1953 and that's how it turned out.

I think that the NCRS bookstore sells a reprint of the last edition of the 53-55 Corvette P&A Catalog.

Re: 1955 Spindle Support Numbers

John, Joe's correct - the "blue cover" 7/1/55 Corvette parts book group 6.023 Support, Steering Knuckle; left is 3706021 and right is 3706022. Give Gary or Eric a call to see if they have the reprint. Gary....
