Slotted Drilled Rotors for a 70?

[crj1968]

Anyone using slotted drilled rotors on their 68-72?

I see Dr Diff sells some but they are listed for 73-up spindles.

I put these on my '68 and they fit perfect with the current spindles and 15' wheels.  I would call Cass, great guy.

Thanks Nacho I saw those in my searching but wasn't sure about size.

303. Thanks also- how did you use 11.75" rotors? You must have changed out other parts also?

Or maybe these are stock size

The 11.75 stage 2 kit from Dr. Diff will fit 15" wheels. I got it with the knuckles, upgraded the pads to EBC, and the difference is amazing.

I am installing this kit right now on my 69.

That would be ideal but I just replaced my ball joints, tie rods, hoses calipers etc... pretty much everything but the rotors. Plus I still have 14" wheels up front right now. 

BTW when people refer to 10" rotors,  it's really like 10.8"  correct?

I went for the same pieces for 74... Stock size. Remember these are made basically as a straight replacement part

Gotchya, but not the exact same ones for a 74 right, because the spindle is different 73 and up.  Dr Diff sells a spindle adapter thing which open me up to more options.

But then again, how would I tell what year my spindles are?       

[Nacho-RT74]

you can tell by bearings PN. Can't recall which one is diff between earliers and laters, I think inners... And check on rockauto itself for it

But also check this info:

Yes, although I have called 11"  and some refer to 11.75 rotors as 12".  The oval track guys, because of wheel rules, can run a 12.19x1.25 rotor, which is about the biggest you can stuff inside a 15" diameter rim.
