I fit the same description as you. I quit making deadlines because I never was able to meet them. However, this deadline 'must' be met.
My goal is to have the car sitting on the ground with all the suspension done, rearend setup, driveshaft ordered and installed, headers fit, trans lines made, brake lines fitted, brakes installed, steering installed, power steering lines made, ignition setup and installed, prewire the car, fuel lines installed AND motor fired. My goal is to basically have this a driving car within the next three weeks. That goal is really not a tall order if I can get through all these snags. I'm only doing mock up right now to get everything to fit before anything is painted/finished.
If I can meet my goal, then take it all back apart and prep the car for paint and paint it.
As far as people around here that have more experience to deal with the rearend, I already tried that route after deciding I was not able to get the yoke to slide down far enough. I dropped it all off to a guy I know that owns a speed shop. I get a call from him the next day telling me the yoke is a 10 bolt yoke. I never took any measurements from it, so I asked him, over the phone, to measure the seal area of the yoke. The measurement he got was for the 12 bolt rearend and not a 10 bolt, as the 10 bolt has a larger diameter yoke in the seal area. I spoke with Moser, today, and we decided I send the yoke back along with the pinion this time. I should have sent the pinion to them in the first place, but oh well. Hopefully they can get it taken care of the problem for me this time.
Another thing that does not fit...oil pressure sending unit

The sending unit that came with the VHX gauges is too fat. It hits the intake right at the block. I need to source an adapter that will lift the sender further off the block.
That is all I have tried to fit at this point. I need to get back out to the garage, but am worried something else may not fit
