A big thanks to Aaron and Jeff, now I have a solid grasp on this build.
I tore the car down and cleaned all the parts. I found the backbone to be barely glued on. In following the instructions, I have sanded the main chassis and backbone.
I glued the back bone on and let it sit for a night. I recieved the center diff assembly from Aaron and the front bulkhead from Jeff. I bought a factory motor mount off Ebay as it was cheaper than the purple one, state side, and included bearings.
I have enough parts on hand, now the build can begin.
I rebuilt both front and rear diffs. I have heard horror stories about getting these apart. Luckily there was no issue. I was able to take them apart, clean and rebuild them. They are not perfect but much better. I left the front a touch looser than the rear. I also cut a top brace out of fiberglass sheet to further brace the chassis against flex. I have to dye the brace but I'll wait until I get a better front shock tower just incase I have to dye that as well.
More updates to come
