Hi MBTJC. Iam in the process of doing this convert. Yes, it is not easy as they say. I was going to just replace the chain. however, I noticed every tooth on the single cam sproket was chipped. It is a wonder the car ran at all. It has 120k. The dbl spocets are only $30 a piece via Benz binn. The crank and intermediate gears are roughly 137, and 67$. respectively. Let us know how you did! And good luck! les
