Very similar frames, I have a 1981 110 engine in a 1985 125m frame and atc90 wheels. I used the 125 wire harness with just a few modifications.

I can answer a little bit here. Not up on 110's and 125's too much. The US90 frame (1970-73) didn't have a removable front engine mount, I'm not sure about the 74 model. After that the 90 frame had a removable front engine mount. I put a 1980 110cc in my 1972/73 frame. The 110 is 6mm longer I believe so I had some trimming to do. There are going to be a lot of subtle differences once you start looking at air box hookups, axle/brake configurations etc. Can we ask what your plans are? Might help with a more definitive answer.
