Ok guys, I want to swap the chuck style, pumkin housing from the rear of my '53 chevy, 3/4 ton with the rear of a '67-'72 chevy as described in the following article:

http://www.oldgmctrucks.com/page0276.html

I found a rear in TX the guy's willing to ship for me. He said its a "Eaton HO 52 non-locker, removed from a 69' Chevy with coils". The photos for his rear are here: https://picasaweb.google.com/prpytlik/RearEndInTX#

and the photos for mine are here: https://picasaweb.google.com/prpytlik/MyRearFrom53Chevy34Ton#

According to the article this should be the one I want shouldn't it? The only number I could find on mine was 3699505 but I can't make heads or tails out of it. Could anyone give me some advice - like telling me it will work (or you know for sure it won't). I've had no luck finding this where it's either close enough to go get or where the guy's willing to ship. I'm just afraid I'm gonna buy this and it's not gonna be right (I'm gonna verify with him its a 2 wheel drive with auto according to the article). He want $100 for it and the "guestimate" to ship a box it will fit in that weighs around 75lbs is about $50. Should I take the chance? I really want to have a rear I can go 60 mph in. Any advice appreciated.
