I see lots of kits available from ebay, summit, etc. Anyone have a recommendation for brand/supplier? I imagine this has been asked many times, but I assume a 727 kit will not work on my 904?]
I would recommend using a good local supplier if you have one in your area, such as Transtar Industries. Many of the kits work just fine, but if there is a clearance issue during reassembly, a good supplier can work with you to get the parts you need. Another good way to go is using a specialty shop, such as A&A trans, Cope racing, or TSR racing. The parts are all the same no matter who you get them from, unless you buy a specialty part one of them makes on there own.
