Magnum V belt conversion

I did look at a pulley set but at $240 + shipping + import tax + customs charge = $440 , i'm fitting LA parts on a Magnum so its already a mix and match, all the pulleys i have are the same V groove and the correct diameter so as long as they are lined up correct with the right belt i don't see any problem. All i really wanted to know is confirmation of V belt type and what configurations people are using.

Yep, and getting them lined up will likely be worth $440 by the time you sort them all out in a land without Mopar-laden salvage yards (which is also Midwest USA). I've played the pulley game. I do not envy your position. I don't know where the Magnum spacing differs. Can't help you there (not that I could help much to begin with.)
