Sorry for the late reply.
The T5 is a very similar shape, but the T10 is more of a direct swap for the Saginaw. You will not need any crossmember modifications. You can use the Saginaw transmission mount, and your crossmember and driveshaft (with a front yoke change).
Before you buy any shifter parts, first make the Saginaw shifter bracket fit the T10 so that the shifter will be the same distance from the front of the transmission as when the bracket was on the Saginaw. Also be mindful of the left/right location. Then, your shifter will come out of the floor in the right place. Measure, measure, measure.
Don't buy a different shifter. You already have all the parts you need. The 2nd gen Camaro shifter has an offset lever (where the handle bolts to) because the handle comes out near the center of the floor. The handle is then bent towards the left. Your shifter comes out on the side of the floor with a relatively straight handle. When you fit the shifter in the same 3D location in space as it was on the Saginaw, you can use the same hole in the floor and the same handle that you already have. When I suggested a 1955-1957 shifter handle, that was assuming you would use the T10 mounting holels and make a new hole farther back in the floor, and would need the U-shaped handle to get around the front of the bench seat.
I think the Shift levers from the Saginaw will fit the T10, but not certain. If not, see how much effort it is to make them fit. If not, source new levers. They are hardened, so beware.
The 2nd gen Camaro shift rods will be longer than you need, because the shifter is located farther back on the transmission.
I feel you already have more than enough shift rod length, since your rods already have a lot of extra thread showing at the shifter end. The only challenge I foresee is modifying your reverse shift rod to fit. It may have to be shaped like a U rather than straight.
Keep us updated! The result will be satisfying.
