400e frame gives you more room.. That's what I gonna use for my rat rod Hudson.
Once I figure out wheel spacing.. And drive gear mod.
Blinding the middle wheel will give the clearance..
Using a can motor.no problem with spacing... Once gears are adjusted..
But to look right think you need to keep the large wheel.
And extend the frame... I have an mth 400e ..which I was going to cannibalize.. Use the motor..its a can motor..its all apart..
And I have a 400e I put together..by piece. Which will be my Hudson.. Frame needs to be. Cut and expanded.
