Well, the m48 in question is a 25mph version, with a stuck clutch...
And we have the a35 and will make it work, haha.
Having yet to drop the subframe off the VA, I can't be certain. But I think a bolt on a35 would be easier then trying to swing-mount an av7/103 motor.
We shall see. Hopefully begin disassembly of the Bat this weekend.
