Good job on the conversion, a first for that lens AFAIK. Pay no
attention to people that criticize your workmanship, you managed to
mount that flange with all 4 screws and that's what counts.
I haven't seen that lens in person but I assumed that rear lens
element would be bigger than it actually is, it actually looks to be
about the same size as the canon 50mm f/1.4.

The rear element of my Canon FL 55mm f1.2 is 40mm, 2mm bigger than rear element of the Canon EF 50mm f1.2 and it still fits inside an SA mounting plate with at least 2mm to spare all round, as long as you remove the three internal bezal ring mounting lugs of course.
