Rough measurement of 4bt engine is about 38" needed from front pulley to transmission adapter. Seems like it will fit without any serious wrangling. But who knows until it happens! I'm also switching to an electric fan too which is thinner than what's currently attached to the pulley.

I can't allow myself to think about reusing the "taco truck" (what my neighbors have nicknamed it). But sheesh, could get a super cheap 6bt that would likely fit the original mounts... would only need a transmission adjustment... and some cab that has the length.
