The Stovebolt Site Forums The Parking Lot Tons 'o Fun Found DRW with Disk Brakes: Help ID

I recently found a Dual Wheel rear end that I'm trying to identify. Could use some help on this one !

Owner told me it came out of 1978 short bus with 350 v8, 400 TH auto....he drove the bus and thinks it is a 4:10 rear gear. What I see tells me I don't know what the heck I'm looking at. Thought it should be a Corp. 14 bolt, but no rear cover ???

The facts: DRW, 10 lug nut 19.5" wheels. Backing plates appox. 48" apart, out to out on rear tires approx. 84". Spring perches 40" on center + or -. Center pumpkin come out the front with no rear cover. Casting #'s on calipers tell me Chevy/GMC ....I'm thinking this is an H110 with 5:38 and taller tires might have made it feel like a 4:10 to P.O. Don't know if that would be considered a P-series or G-series ?

Sorry did not get any photos. I was to busy unbolting a set of 8 lug x 19.5's off of another rear ... "Made My Day"

So what do you guys think ? H110, H135, AAM ? I have an Eaton and a 14 bolt and it does't look like either one of those.
