Input Bearing Retainer Question

That may be true, but mine also has 1.92 (2nd) &1.4 (3rd). It's a 4 speed not a 3 & over. Don't assume anything when it comes to used parts.
I don't assume anything. Not many people on this board can recognize a gearset swap when the get one. I've done plenty of them myself, but I lose all the OD transmissions I get. I take the fasteners, the bearings, shaft, side cover parts, and donate the rest.
