need some help with disk brake conversion

[jamon8]

my truck is a 65 and I am using a 79 c15 with the 1 1/4 brakes so I can keep my wheels and use 6 lug rotors.

my question is about the idler arm. the setup on the 79 is way different than the 65 and I want to know how to mount it so I will have the proper steering alignment.

also is there a cheaper way to buy the rotors or am I stuck paying an arm and a leg for the conversion rotors.

i plan on using all the brackets from captain fab
