I knew the question was coming on costs. I'm working on getting the latest prices for parts together. The last time I bought gears they had gone up in price so I don't have good data as of today. Will go through the pricing and try to post some DIY prices and where to find the parts. I may be willing to do some custom installs myself but don't want to get tied up in a big operation. Ther is an increased "fiddle factor" with the these starters. You have to want one real bad to add the weight and additional complication to your model. Some of the local guys I have helped love them and some have not.
