Hello

I am in need of the current GM part numbers for a vented gas cap, radiator cap, and parking brake handle. These are for a '70 SS. I know they won't be exactly the same as original, but they will be close and made by AC Delco. I went to the dealer today and they were very uncooperative. If anyone can help me out, I'd be grateful. Thanks!

gas cap vented- non eec (9391449) opps typo 3931449
gas cap vented-w eec 3997480

radiator cap 6410456

parking brake handle 3960789

These # may have changed or may not be available.

Here is a number for a 15 lb vented GM radiator cap 10409635. says ac Delco on the box(AC DELCO PN RC27). It cost me $4.19

Marina Blue....is this radiator cap similar to the original cap? Also, if I have the original part numbers used in 1970, can the dealer find the new replacement part number for the parts I'm looking for? Thanks for any help.

Bill Heard chevrolet , Sugarland, TX has 1 1-800-420-4249

I should have noticed the typo myself. I also have one. GM has plenty. Plan to pay about $15 for it.
