steering u-joint ?'s

[GM Muscle]

I've got a small issue with my camaro and did a search but didnt yeild any black and white results.

I have a stock 69 column-non tilt, floor shift. Im using an IROC steering box and half height aluminum subframe bushings. I put a lsx in it with 1' set back mounts and hooker headers. the headers run close to the rag joint and i dont like the the idea of heat on rubber. on top of that the rag joint is already in a weird stretch/ bind from the raised subframe.

My question is, what U-joint can i/should i use? i would like to eliminate the rag joint all together. i am not a creature of comfort and i dont mind doing a little fab work if i have to.

Any part numbers or suggestions to help me surpass this obsticle?
