Where can I find a factory posi rearend

[Gagecampbell82]

I never thought about not reusing a old tc. Although I knew the fluid ran inside it too. And my trans does shift fairly hard, and I do have to build up some rpms to get it rolling too  But I've always wondered if it's really a 2500 or not.

 And I'm not sure about how many rpms i have to build.
(Can't get my tach to work with the msd box, apparently I need a signal filter or something they make)

 as far as I know my rear end is still ok,  but I do here it  winning a little at highway speed, which I assumed is because of the trans and stall. It won't be driven much this winter but I'll be buying up parts to throw on it early next spring. I Have been re doing all the rubber brake lines, ball joints, tie rods, and next will be all new bushings and bump stops then wheel bearings rotors and ect. Im gonna make it stop and ride safely before anything, because what good is a built motor in a wrecked truck. Lol.
