Thanks for the info on your setup. I might try the top hole and see what it does, I'm sure like everything else it might be a royal PIA to get the bolt holes lined up.
I talked with Inland drive shafts yesterday and it looks like since my rear diff yoke is only the 1310 he was going to do the same size in the front. I think my distance 59-5/8" from the end of the spline to the face of the yoke. My other concern i the u-joint clearance on the tranny since since the crossmember is so close compare to the long nose on the old 700R4 I removed.
