Man I totally screwed the pooch on the placement of the motor - used the drawings provided on Amazon - not sure if the drawings are wrong or I screwed up. But the motor is larger than the dimensions said. Anyway I cut away some plastic - lost 2 mount point screws but hopefully 4 will be enough. If not I may have to make an adapter plate or something. Also my motor mount holes did not line up. Have to print another one tomorrow.
I was able to salvage the original shaft from the plastic HL transmission - bought some 6mm spacers from McMaster-Carr and drilled them out to press onto the knurled HL shaft. The gearing works.
