yeah ive sided witht the 4agze, aftermarket computer(microtech?) and am looking into the commodore breaks and diff setup with LSD.I spoke to a guy to other day who is helping with the conversion and he said the T50's bolt up the 4agze's but has to be a 22spline box with some side plates otherwise an internal bearing goes!? so is it the JDMt50 i need or can i get a JDM bellhousing and through a 22spline box in? ive set a rough budget of 8-10K but i also have to cut rust, redo the paint, get some half decent rims, suspension, gauges, racing seats and any other involved costs for the conversion.
