CPP grand slam question

[TxRat]

I'm trying to figure out which way to go with buying the components to lower the front of my truck properly.







here's what I "think" I got.

I think the crossmember is original to the truck.

the control arms are early as they do not appear to have press in bushings. stock spindles(don't know year and 1 1/4" rotors.

I would like to buy the CPP grand slam kits

My concern is can I use the 1 1/4 rotors with their spindles or do I need different rotors. I know I can ask them just thought I would ask here to see if anyone is using 1 1/4 rotors on the CPP dropped spindles..

I guess the simple question is what width rotors does the grand slam basic kit use. 1" or 1 1/4 rotor so I know which rotor to buy or I can use my old ones...
