I see some suggestions of using a universal or one from another manufacturer good ideas but impossible to find the specific specs. This part is a potentiometer not a simple make or break switch. Without knowing the values at each detent position, placement of the harness plug/contact relation and finally mounting and clocking it for the specific application makes it difficult to narrow down. I just ordered a 5304500591, it supposedly has the same 8 positions and a 4 contact harness connector (mine only uses 3 of them). Need to use a die to cut threads in lower part where shaft meets body hoping that is the extent of modifications needed. I guess I'm the guinea pig.
