so would there be anyway to get an lsd for my current rear end? anyone ever seen this before? http://www.tractionconcepts.com/1980-1986-Datsun-720-Truck-H190-Diff-Lsd-Kit-p/tcxda4621.htm

im doing the swap myself this summer when my gto will be capable of being driven, as for the rear end it says he35 on the plate. this is the best pic i could get out the plate since it is so faded

i have a 1983 and a half 720 extended cab so its technically Nissan. i am building this truck to basically out do my father's 88 Mercedes 300ce. so far i have a new motor that should do the trick horsepower wise, but im having issues finding information about the rear end, i dont know what differential is in it, i am looking to build a posi for it. as for other information on my truck; as i said it is an 83.5 Nissan 720 extended cab currently has the z24 motor in it but im going to swap the motor for a newer ka24de-t i haven't decided on a new transmission but it currently has the stock 5 speed (that i also have very little information on), and just a plain open differential. any information on the rear end and the transmission would be greatly appreciated. thank you
