I bought a Compufire module for my '68 Bus with a SDVA. The problem is it doesn't fit. THe little nob that is supposed to go in the hole in the base of the dix plate doesn't match up when I screw the thing in. AS a result, the module rides up to high and interferes with the rotor. Anyone ever succesfull install one of these things in a SDVA? What sort of modification do Ineed to make? I was thinking about filing the nob off, good idea or bad??
