Urgent Help to Identify part

[pontiac_bashee]

I got ripped off on eBay and according to the auction this part ( 9799127 XF ) was off a 1969 428 with no power steering or air conditioning. Why it has 2 belt grooves I do not know but if anyone has the microfiche or part # book please check the part number for a 69 428. According to what I found out so far a 428 with only an alternator has a single groove pulley.

This is the pulley I bought. To bad the seller took pic of ONLY angle that did not show terrible chrome peeling and rust. The side and back are terrible and the rust that is showing at angle is hidden by the brown reflections.
He said that item was ok when he put it in box but rust that deep does not develop that fast and there was not chrome flakes in box.

You are correct. Pontiacs ordered without power steering and a/c, regardless of chassis or displacement, in 1969 did indeed use a single groove pulley on both the crank and the water pump. Steve www.pontiacheaven.org (http://www.pontiacheaven.org)

go to performance years home and click on parts number system. strangely the same part# was used on both the 1 and 2 groove pulley in 69 and 70 http://forums.performanceyears.com/groupee_common/emoticons/icon_confused.gif

There is a code after the part number that I think identifys the difference. The problem is that the guy who I bought the part from said it was a no air and no power steering car so there should ahve been a single pulley. That causes a problem with alignment of the lower pulley.
