A 3100 and 3600 don’t share the same frame (different width and length) so the spring mounts won’t line up. The 3100 doesn’t have an intermediate u-joint like the 3600 does. Anything is possible but the amount of work involved would not be worth the result.
I have heard that there are 4:11 gear sets that could be swapped in the pumpkin. Maybe a fellow “Bolter” could verify this for us!
