I was speaking to the rep at Broward Powertrain and he was asking me what type of driveshaft I have. He mentioned certain types. What type/model driveshaft comes stock for a 69 GS400 with a TH400? What type of U-joints (1330??) The reason for this is a conversion from a 8.2 to a 8.5 rear. Thanks for any help.
