We are installing my kit from classic parts today, the local shop is letting me help their mechanic, when i opened the gears there was a Filling Station Sticker in them. I was told by classic they don't purchase theirs from Patricks anymore. They said they have sold I believe 29 of the gear kits with two returns on the gears. I considered Patricks but kinda figured most all of them are probably coming from the same set of vendors. So far almost everything i have purchased for my truck other than maybe three things have came from classic and i have had zero issues with any of it, and there technical support has been great. They also said they dont have instructions but could get me a copy of Patricks which I already have along with Sweets page. The bearings do seem to be well made, we use bearings from all over the world at work with no issues, so i don't anticipate a problem.
