Kframe

The basic frame is the same but the metal stands made on them are different. You will have the biscutt type, 1972 back and the spool type, 1973 up.

correct. I have a 71 scamp originally equipped with slant and the k frame wouldn't accept the 340 im putting in it. mounts were off about an inch or so each side. shumacher makes adapter mounts but I just went out and bought a used k member.
