The kit that I got is a good quality kit and the price was right it just did not come with synchronizers and in most kits they are separate do to being year specific plus more often than not with the SM420 they are not bad and reusable. I just prefer to make it all new.
This transmission even being out of production for decades is very popular with the 4x4 crowd and there for well supported by the aftermarket. I am looking into whether anyone is making improved carbon fiber synchos.I am planning to go to Novak for their billet front bearing support and shifter retention kit,unless I find something I feel is better wile shopping for synchronizers. I am not in a hurry for the transmission so I am taking my time and doing research now. The transmission I found to rebuild was built long after regular production of the SM420 ceased it is a military version with a heavily ribbed case built in 1987 I did not get a top cover with it but cover from my 57 parts truck fit and works good I just want to mod it for a reverse light switch.
