Hey,

OOC: Is it possible to change a .15 OS CV into a .12 OS CV buy stuffing all the .15 OS CV stuff onto/into the .12's crankcase?

It'd probably be better to buy a new engine but just curious if its possible & if its not, then what is needed. Kinda want to know a bit about the differences about the internals betwwen a .12 & a .15
