Magnum V belt conversion

OP, there exist white books on nothing but Mopar Pulleys. They will tell you the part numbers for which ones fit what with whatever options. Find one of these books.
Get ALL of your pulleys and brackets (numbers) from the same vehicle. Most of this is reproduced in the states and you can buy new as a set. It is NOT recommended to mix/match from various vehicles.
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.
