C33Laurel

I've put an rb26dett r32 gearbox in my c33 laurel and I'm having some muck arounds with the driveshaft. I need to make a one piece as the hanger bearing bracket is way off and to much effort to custom make another bracket, but the gear box is bolt on and so is the standard laurel lock diff. How can this be done but still have play backwards and forward? It must need a yoke in one end? Please help

I currently have a Nissan c33 Laurel, which has a 25det with about 450 hp. I'm currently turning it Into a dedicated drift car and have a blown 20det gearbox in it due to the yoke on the driveshaft has been ground out and was leaking all the oil out hense the blown gearbox. I'm looking at gearboxes and 20det ones are about $400-$600, and 25det conversions are about $1800. I've also heard that you can put straight cut gears into a 20det box to make as strong as a 25det box for about $1200. Just need help on any opinions on what type of gearbox I should get?
