I found a company that has a disc brake conversion kit that uses your factory stock drum spindles. It is about half the cost of just about any other company's kits . First of all; are any of you familiar with "ECI Hot Rod Brakes" and are their products any good? And second of all; can I use something like RMS upper control arms with them? Or will I have to go to an upgraded spindle anyways to do that? I'm only scrimping on the brake conversion because I don't wanna have to use 1/4 of my budget for front brakes if i can help it.
