toughening up a toploader
hey guys, my toploader is a lil noisy in third and a lil slow to synro second, its a 30yo box and neva been touched, it's done henry proud! but it's due for that long hard earned freshen up. does any1 know where to get rebuild kits for these boxes, bearings syncros seals gaskets in 1 kit and do they make these kits wif betta bearings so they can take a bit more punishment torque and hp wise. I want to do this job myself so any advice would also be appreciated.
