I want to buy the mounting bracket, pulley, fuel lines, belt and fittings to install 2nd CP3. Who sells these parts? I already have a CP3 and a dual controller.
The truck has a dual alternator so I think I have to remove 1 and install the CP3 in it's place, is this correct?

either that remove the second alternator or the ac. Might not need a belt since it already has the long one for the dual alternators. I've been waiting forever trying to get a dang kit lol

Just curious....what size is a dual-CP3 pulley? I believe they are made to the size of the harmonic balancer?

Also, whats the size of the CP3 shaft? Is it tapered?

I think the belt run on the balancer is 7-1/2", but it would probably be better to measure the circumference.

My spare CP3 is buried up in the garage loft, so I cant measure the shaft.
