So, i'm swapping my 82 longbed from a turbo 350 to a turbo 400. Does anyone know if there's a 1 piece driveshaft for the turbo 400 in the aforementioned longbed? if so, what years, options would I need to be looking for to find 1 in a junkyard/craigslist? Eventually i'll have a custom 1 built after I make it a shortbed, but for now a stock one will work. Thanks
