Driveshafts....if you just modify what you have it will be aorund $100 to shorten the back. The front will need retube so this will be more like $200. If either need replacing then more. I had to have a front made and I think it was like $350. It's been a while so others might have newer pricing.
So if you factor the bellhousing ($100), Driveshaft ($300), Transmission ($200), Short shaft kit ($200), Clutch ($100) you end up around $900 and that hasn't paid for oil, gaskets and other misc. A Teralow kit is like $850. It doesn't come with all the bearings you need but it does have the gasket & seals. I have all the Timken numbers for the Dana 20 bearings so you end up at about the same money without the driveshaft angle issues and transfer case shifter issues (it ends up moving back toward the seat which will require something to be fabricated).
Anything is possible if you don't know what you are talking about.
