I have sold most of my parts, I just have some spares for this and that left from my 85. Really the only thing I'm looking for is the shifter base for an R151F, but they are a little tough to come by.
Is this what your looking for? i know its not the one for a R151f
If its what your looking for try the dealer. i bought one for my moms R151f at the dealer. cant remember the exact price it was around $40-$50 bucks.
