Welcome to the board from the Pacific NW! Try doing a search on the board. This was recently covered in a post. You'll find a 50/50 split on whether to keep the 2 piece or go with a 1 piece driveshaft. Properly rebuilt, a 2 piece will last another 30 years. However, it can be expensive and I prefer a 1 piece myself. I had one in a C-10 LWB for years w/6cyl and it was soooo much better considering I never had to replace any carrier bearings or fear they'd leave me stranded again. I had 3 go out on me within the same amount of years. The 1 piece will be easy to measure for and no problem to make, but you'll have to completely remove all the bracketry for the carrier bearing mounts. Given your goals, I might stick with the 2 piece and have it rebuilt by a good shop.
