Help with ID'ing a Rear End

I have a 37 Ford, and was told the rear end is out of a 67 Olds Delta88. It is a Pumpkin Style chunk, no rear cover. On every web page relating to rear ends, none of them say anything about a Pumpkin Style. It has 10 bolts holding the chunk in, and I was told it was a 3.23 Anybody with any info, or can direct me to web page I would appreciate it.

It sounds more like a '55-'64 full size Chevy or a '55-'64 Buick-Olds-Pontiac. The Chevy is a 10 bolt but they didn't have a 3.23 gear. The choices were 3.08, 3.36, 3.55, 3.70 and 4.11. Not sure about the B-O-P gear choices but the ring gear had 12 bolts but I don't know how many bolts held the pumpkin in. It could also be a Ford or Mopar unit from well into the 70's. The Chevy will be kind of flat on the top and bottom when viewed from the rear and the B-O-P will be round.

A '67 Olds Delta 88 would have had the 8.25" 10 bolt B-O-P rear end with a 10 bolt rear cover. Not quite the same as a Chevy 10 bolt but not a bad rear end. That's what the GTO, 442 and GS were equipped with.

The early Olds was the hot thing, so when trying to identify it don't let the gear ratio be a determining factor until you have actually counted it yourself. If you post a jpeg, you'd get it identified quickly.
