Hey Paul-
I 'thought' about rebuilding it, but here's the thing. It turned out to be a Monte Carlo transmission (non HO) which Jack Cotton said can actually cause problems even with the BRF valve body and governor. The BRF transmission I bought, turned out to be a BQ valve body (and the 1-2 shift valve is no good) we tried taking it apart and sanding it down, but after running that VB in the trans, it killed the clutches, yikes. I know what you mean about assembling the valve body, when I took it apart, I was like WTH ARE ALL THESE LITTLE PIECES! haha. Good luck to you Paul!
