be careful of corvette and other gms with IRS, they will use a driveshaft coupler.
if you just do a google search for "GM driveshaft lengths" and add the word "forum" you will find a lot of listings, the 4x4 guys especially like having that info

We are thinking on the same line. I'm not too familiar with post turbo 350/400 related pieces like yokes.
My buddy had an apple bin full of driveshafts that I could raid and another buddy who owned a wrecking yard stacked every driveshaft they took out behind a shed. I went through that batch more than once.
I'm a firm believer in keep it as simple as it comes when it comes to parts that might fail on the road outside of engine and transmission. I keep it to the concept of somethings call for a tow rig to get it to where it can be repaired or hauled home. Mostly the engine and trans. If most of us blow an engine we are going to figure out how to get it back home, Same with an automatic trans for the most part. Pretty much for a third member in a rear end. Those three items call for finding a trailer or calling someone to go get your trailer and come get you most of the time. Or find someone who you can stash the truck with until you can get back in a week or two to get it with your tow rig and trailer.
On the other hand Alternators, starters, distributors, carbs, flex plates, clutches, U joints and wheel bearings can usually be swapped out in a few hours if you can find them.
There are exceptions, Back in 1964 I drove past a guy from the midwest on the way to work and on the way home who rebuilt a straight 8 Buick on the side of the road with his family camped next to the car. He actually dropped the crank out the bottom with the block in the car and either had it turned or replaced it. I didn't have time on the way to work to see if he needed a ride to the machine shop or parts house and it was too late on the way home. That is the exception.
That said, I have used combination joints a number of times and they worked fine but there have been a couple of times when I couldn't get the right replacement and had to wait until the parts house had one shipped in. That might be a road trip to a cool event or vacation in the truck deal killer if you are stuck in a motel in po dunk junction for a day or two waiting for A U joint.
