A body 8 3/4

What's the specs on it, is it a limited slip, do you know what gearing. Any info would help including year mileage, is it a 742 center section?
It's a factory 68 A-body rear with standard small a-body brakes. The axles were welded up and re-drilled to the large bolt pattern. I put new shoes, hardware and drums on it about 20,000 miles ago but the shoes are worn quite a bit so I have a new set to go on it. I also installed new axle bearings and seals when I initially rebuilt it about 20,000 miles ago. Right now it has a 3.55 geared 3rd member in it that I plan on keeping but I have a 489 case with a brand new Dr. Diff clutch type sure grip and all new quality bearings (Timken or National) I'm about to assemble and have 3 gear ratios to choose from. I have a 2.76, a 3.23, and a 4.11 set. The gear ratio choice is up to the buyer. It'll have the small 7260 A-body size yoke. I got it out of the car but haven't taken pictures yet. I see others have messaged you also. If mine is of interest to you PM me and I'll give you my ph number. Thanks, Tracy
