I had those guys do there 9 roller bearings and drum modifications to my C-4 but I haven?t ran it yet but when I got the parts back from them I didn?t get the same drum back for some strange reason my 26/26 input shaft (aftermarkets)would no longer fit into the drum but a 24/26 input shaft would fit.So now they want me to send the drum and input shaft back to them (at my expense) both ways.So now when I get the drum and my 26/26 input shaft back they had replaced the drum with my correct drum with the 26 spline but for some reason now one end of the input shaft fits the drum but the other end doesn?t fit the 26 spline in the converter and the input shaft looks totally different (stock input) but I sent them a aftermarket input shaft.So having another conversation about it did nothing to fix the problem I just gave up on it as a lesson learned.
