I'm working on my buddy's truck he's got a 2 dr exploder with a EB 9" and 44 we put a 302, 435, and a 205 in it. The front output on the 205 is a 1310 and he needs a cv on it. The only cv's I've seen are the ones that are threaded for bolts thru the yoke. Is there a style of cv that uses straps? And what type of vehicle could I find it on? Or is there a different style yoke that I could put on the 205?

I`ve never seen a CV shaft that attached other than with the through bolts like you describe or with a flat flange style yoke. Call Jesse a High Angle Driveline, he`ll fix you up. I don`t think you`ll find one, but stay away from any strap style of yoke, they`re very weak when it comes to offroad abuse.
