Well I finally got my rearend back from the shop. I dropped it off in December to be narrowed 1.5" (width) so the wheels would not rub the bedsides when aired out. I also had an RX7 differential installed which came out of an 85' GSL-SE with limited slip. This should help give me a little more traction instead of one-wheelie-peelies. I don't want to destroy it though so I'm going to try not to beat on it it too hard.
I also finished seam sealing the bed floor.
Next steps are to do the brake lines on the rear, install the rearend on the truck, and have some friends over to help me pull the bed so I can paint the underside of it. As soon as the bed is back on, I think she's about ready to drop off at the painters for body work and paint. Oh yeah, I need to install the flush mount gas cap on the bedfloor too.
I have a stock B2200 diff for sale if anyone needs it.
I also have one from an 83' RX7 with LSD.
