So changed around the bolts so head is closest to tub, a little more space.

Then was able to get the nuts on the attachment bolts. Got a slight tension on them, then heated the tub from the inside at the point they touch. Tightened bolts all the way and added more heat. Tub moved in nicely. Underside had a bulge so propped it up with a 2x6 and let it cool. Perfect imprint of the bolts in the tub now and no pressure on it to rub thru.

I had tried to come up with a jig to push in on the tub while heating, then tried freehand, clamps, boards, nothing was going to work. I was about to use longer bolts just to get it started, but then was able to get the nuts on.
All worked out good.
