I bought a 3" BDL set up cheap. I tried putting it on my 76 FL and found out the clutch basket wasn't thick enough for my 4 speed. The engine pulley fits OK. I called the guy I bought it from, and he said it was on an 84 1/2 shovel with an EVO style 4 speed. Anyone know if I could get the 4 speed hub, and use the same BDL basket?
