question about drop spindles.

[ivorton74]

I was lookin at drop spindles and i see some go on trucks with 1' rotors and 1.25' rotor. which spindles would work on my 74 c10 and how can i tell?

Measure your rotor width.

[lolife99]

Your '74 should have 1-1/4" wide rotors.
All you have to do is measure them to know for sure.

I think the 1" rotors started after the 1981 model year,... BUT,... you could also get 1-1/4" rotors from 81-87.
That's why you have to measure.

i just went to some auto parts sites(napa, rockauto etc) and all the rotors ive seen are 1.28 inches thick. so i guess its 1 1/4 spindles for me. but i'll still check em. i plan to get the spindles around income tax time. i ordered my ebay flip kit 2 days ago and thinkin whether to chop my stock springs(1 1/2 coils) or get summit 3 inch springs. im tryin to lower the truck soon. what should i do?

How low are planning on going...the more spring you can keep the bettor the ride will be.
Those springs your chopping are 30 years old.

exactly, if you don't you will have the same prob I had some 15 years ago.. bought belltech drop spindls and had to swap to smaller brakes/rotors. (83 C10)
