Re: ‘76 GMC LS Swap

So the engine and trans are in, buuuuut...... the driveshaft doesn’t fit, naturally. Because why would it? Haha. I was confident that the Dirty Dingo sliders were gonna put everything in the right spot (mostly because I was told that’s exactly what they’re intended for) but that’s alright. Took my measurement, and it looks like I need a shaft made out to 78.5”. Dropped my shaft at the shop this afternoon so they could get started Monday. It had a one piece aluminum shaft in it that came out of a late 90s G series van, as far as I can tell. Big beefy thing too. 4” dia at the ends and stepped up to 5” in the middle. STOUT. These dudes are supposed to be the best place around though, and they’ll get me going. To the tune of about $400. Which is great because we all just have an unlimited amount of money to dedicate to dropping an LS in an old work truck.
