The reason i posted that link for the $220 kit is because i have seen people on here list the drivetrain.com kit many times before so i figured it was the kit of choice when there is a cheaper kit on allstategear.com. Now for how the quality is between the two that i have no idea but i did call allstategear and they grabbed the kit out of inventory to see what all was included. Brass synchros, all bearing and seals that are included in the drivetrain.com kit. How ever allstategear does not carry the "small parts kit" and "dog & spring kit" in which you would order those from drivetrain.com
