Here's the other side without the shifters in the way.

By the way, Northwest Fab makes an adapter that is .600 thick to bolt these 2 together. It what's can be used with a 4x4 trans without cutting the shaft.

Had to give the adapter foot a trim on the little cast gusset, so the pan won't hit and can be easily removed.

Been working on this swap some more.
Almost put $400.00 out for a crossmember setup then decided to see exactly why my crossmember won't work. Well, it's too narrow. I did some measuring and found if you cut it right below where the upper and lower pieces bolt together, it dropped right in.

Had to make adapter plates. You can buy these from Holley for $90.00. Or I went to my local metal supply and bought 2, 6x6x1/4" plates for $5.00. An hour later with some cutting, grinding, drilling, tapping and painting, this is what you get. (Let the paint dry over night) I used the old LS mounts and the stock, poly small block mounts for patterns.
