Great diagram, thanks. That answers the questions that we had.
Although it won't matter for what he is wanting to accomplish, notice that they have the math wrong. On the TH 350 they have the length from the front edge of the trans to the "center" of the trans mount at 22 1/4 Inches, then they have the measurement from the front edge of the trans to the "back edge" of the trans mount at 21 5/8 Inches. It should be longer, not shorter, lol. Some of the other charts online have the PG the same way.
