I'm thinking of haveing the pieces made into a 1-piece driveshaft, so when I get around to doing the 4WD swap on my loyale, I don't have to worry about the center bearing (as it will probably get lifted a year or 2 after I do the swap, so I don't want to weld it). anyone have anythoughts on this?

 

I'm thinking since the diff and tranny stay essentially immobile, and there'd still be a u-joint at either end, it shouldn't be an issue. am I missing something?

Take it to a driveshaft / transmission shop. Tell them how long you want it, which joints you want at what end, and throw down a couple hudnred dollars.

 

Or you can make some L brackets. Weld them into the unibody. Bolt the center carrier bearing housing to the L brackets.

no issues with one piece.

 

i'm with him, if you spend any money on this deal go solid one piece and get replaceable ujoints on the ends that way you're not dealing with problems down the road. the ujoints are already old as nuts.
