GM Pulley ID please
 

I have a GM Cast Iron P.S. pulley that is double deep groove that may be mis-boxed.
The part number on the box is 3941105. I thought that number was for a single deep groove pulley.
The only thing else that is on the pulley is "1A" "GM" and "2A".
Any ideas?

Wrong box for sure Rick. That box is for a single groove high Hp chevelle ps etc.

That's what I thought.
It's been in that box for a long time and even had a 1983 dated receipt in the box with it that had the part number 3941105 also.

IF it's got an outside diameter of 6 & 1/2,it's power steering pulley #3878245 for all 1965-69 Corvettes w/396 & 427 CID....IF

Thanks for checking on that for me Rick.
I just measured the pulley. It's 6 & 1/8, so it must be a different part # than what you found.

Re: GM Pulley ID please
 

Rick..then I believe that's pulley #3834720.
Used on:
*1961-65 Passenger w/Spcl. Hi-Perf 348 & 409 CID.
*1965-68 Corvette Spcl. Hi-Perf 327 CID w/o AC.
*1969 Corvette w/Power Steering,but not 350 CID.
