Reusing Turbo 350 X-Member issues
 

I started to finish up my 5.3/4l60e swap by getting the transmission x-member in place and the tranny bolted to it. My truck previously had a 350/350 combo from the P.O. To save a few bucks, I wanted to see if I could reuse the old crossmember with new hardware.

When I went to look and see if the old Turbo 350 xmember would work, it seems to be a pretty darn near perfect bolt in for the xmember's stock location, but the Transmission Mount I'm using (single bolt style) Seems to be about 3/4 to 1 inch toward the driver's side from the original bolt hole in the mount. I checked the alignment of my motor and it seems to be in right, so is this something normal? I plan to take some measurements underneath the truck at the tailshaft to see if the transmission tailshaft is off by 3/4 to 1 inch or what the deal is. Has anyone else had this issue?

I am using the stock TH350 mount moved back with my 4l80e.
used the stock holes in frame.
Used stock 4l80e trans mount and elongated hole.
stock motor mount with transdapt plates.

I also used a $6.50 TH350 mount (2 bolt style) with the factory cross member. I did need to drill new holes in the frame because I moved the cross member back.
