I will be putting a 390 R200 out of an 81 ZX in my 75 280. Does anyone know if the flange coming off the differential to the driveshaft on the 81 can be removed and replaced with the stock 354 geared R200 flange from the 75 280 in order to use the stock 280 driveshaft, OR do I have to use a different drive shaft? I think I recall someone saying that this conversion requires a 1976-78 driveshaft, although it appears that the flanges could just be swapped out. Any thoughts?
Thanks
