If you're near an ACD jobber or GM dealer you might try 214-1044 or 25532662. I've never tried this but I don't know why not. With whatever you buy be sure to check inside the cap for the o-ring seal. I think that generic -4AN caps may not have the seal.

If you try the GM I'd be interested if you post back and mention your thoughts. I've always intended to but haven't had the need so I never have.
