Thanks Mr.Chevy, I went with what you’re saying. I think I was surprised as I had not measured where to pinion was in between frame members, so when I fabricated the cross member for the upper mounts, I discovered the pinion offset by 3/4” to the passenger side. A lot of scratching my head then occurred and of course re-measuring everything yet again. Then crawling under cab, I measured tranny nose and yep, it was offset, so I’m ok with the offset now. Just a day of WTF did I do? Just gotta go in and weld everything up. I think I’ll check travel of diff first by jacking it up and down to see 4 link work it’s magic.
