Thank you Pat. Glad to see your out enjoying your rig. Your build has been an inspiration to me.
This afternoon, I mocked up the Tom's Off Road, AOD crossmember. The first thing you need to do. Is remove some of the aluminum around the mounting point on the AA, 4R70W to Dana 20 adaptor. The surfaces are machined leaving a large radius around the mounts bolt hole. however the radius does not clear the large bushing washer. So you need to remove the material back to the housing. And remove a portion of the washer to get it to lien up with the mounts bolt hole. You also have to clearance one side of the large poly bushing to clear the AA housing. See pictures below. Once this is accomplished, it's a matter of attaching the AA housing onto the end of the transmission, and bolting the crossmember assembly to the frame. Add the bushing washers and bolts and it all fit together nicely.
