I've put a H190 complete diff into my coupe that came out of a 1200 sedan, my problem is with the bigger diameter of the axle tubes, the U bolts end up stretched out and won't fit the standard coupe lower mounting plates. I elongated the holes and got them on but they don't tighten up all the way and the U bolts look stressed.

I got some flat plates with the diff, should I weld a bolt to the bottom as a shock mount?

I got a set of ute U bolts and plates as I heard the bolt spacing was wider but still looks like i'd need to elongate them as well.
But they have a bigger stub axle diameter shock mount so it may screw me with the coupe type shocks as they mount to a smaller stub axle.

Any ideas?

cheers
