Ok.....making progress............moved UPM mounts to widest and moved axle bosses to Outer settings......got axle bosses lined up and into the slots with little resistance, no hammer needed and tightened down. Have added BP cants and E-rings and Base plate.
My only problem so far is that with my 3 and 6 degree BP cants, when you add the screws for the Base Plate the low side of the Base Plate screw is causing the E-ring to gap by the screw being a little too long and pushing against the plate.
Anybody else seen this? See the gap in the close up photo of the E-ring....... I tried turning it back a few turns but to release the pressure enough to reduce the gap to the Base Plate, the screw sticks up in the way of the toe/heel blocks.
