Need some help. I'm dropping a L96 in my 2009 silverado and a 6l90e tranny is coming with it. I've read that the 4l80e are shorter and require a small amount of work to mount to the crossmember but has anyone swapped the 6l90e into a NNBS silverado? If so what is needed for it to bolt up to the crossmember? Additionally the drive shafts becomes the next hurdle. Any informatiom on that would be appreciated.

Drive shaft will need to be shortened with a 6l90 vs a 4l60, as far as crossmember you will either need to lengthen the holes in the crossmember or possibly weld a plate to extend it, is it 4wd or 2wd
