The Rear End is apart

Took the rear end all apart today except the pumpkin. Found out I have a 37 tooth ring gear and 10 tooth pinion which makes this set up a 3.70 gear ratio. It has the 28 spline axles and small bearings which should be fine. This will be perfect for the Small block 350 engine and 700R4 overdrive transmission thats going into the truck. All the parts in the rear end look great and it even had oil in it. Will have to have the axle bolt pads redrilled for a 5 on 4 1/2 bolt pattern to match the new front suspension pattern. Also will put in new brake cylinders, brake shoes and drums to fit the new drilled bolt pattern. I now have to cut off the old shock mounts and spring perches. New perches will be welded on the bottom of the housing later when the pinion angle is set. This won't happen until the engine and transmission are mocked up and a new driveline is built. I will check with my experts, but except for drilling the new bolt pattern, I think I can reassemble this baby since I didn't disturb the pumkin. That takes an expert to set up if you take it all apart. I may need to replace the bearings, but they are sealed and look, sound and feel good. Someone with more knowledge than I will tell me. Will do it if needed.
I still can't believe I fell into this one. My luck usually doesn't run that way.
