I’m wrapping up the engine swap, late fifties 261. While installing the driveline back onto the trans, new cork rings, new paper spacers, Tires sitting on the ground. I notice that the ball doesn’t quite line up side to side at the transmission by about 1/2 “, It pulls into place with a small amount of side muscle. It seems cocked off to the left. I looked at the axle mounts at the springs thinking they could be knocked off kilter, but the shackles that mount directly to the axle and the springs, I think are dowelled in place, so I doubt they could move out of place. Unless a dowel sheared off, but unlikely. I really didn’t notice this when I disassembled it the last couple of times. I’m thinking might be that the frame is tweaked out of shape. Anyway, it pushes into place and bolts up, and probably will run fine like that, just puzzling over it.

I remember mine being a tad to the left also. I checked the torque tube mounting and then loosened all the engine/trans mounts and made sure the engine was inline with the torque tube. All went together OK after that.

Thanks for the word. I think I’ll try that loosening the rear motor mounts. Transmission, 420, just hangs. Front mounts are not tightened yet. I’ll check in later, Charley

On my transmission mounts, the first ones I had were more square and they were wider. My frame cross member slants up where the mounts sits. So, I found a different transmission mounts that was a little narrower and I think that worker better for my situation.

The mounts on the left (left part of the first pic) sure look like AD engine mounts. Likely different than the ones for '46 trucks.

The crossmember with the angled area for engine mounts is for a 1954 or later frame. It is used with a different bellhousing than the one with the vertical mounts in your picture. Somewhere along the way there has been a mismatch between the crossmember, the bellhousing, and the motor mounts. It looks like someone has modified the crossmember to use the earlier mounts, and probably drilled the holes a little off position. That will result in some misalignment between the transmission and the torque tube, and possibly a vibration problem. Jerry
