Part # Help

[COPO]

I found some gears that look to be spider gears, but not sure of application. Can someone with a Chevy Parts Book tell me what Grp. 5.528 and #384078 are for?

COPO,I'll see what I can do tomorrow.I just tried the GM Dealerworld site that I use at work and came up with nothing.Plenty of old books at work to look through.As I always say "theres more than one way to skin a cat".Try the front door,if nothing there,try going in the back door.Usually I can find something.

Thanks Rick. Looks like they are good for the trash bin.
