Rotors??

I have a set of D/B from a 70 impala on my 65. As you can see from the pics the rotors mount on the rear of the hub and are held in place by the bolts press-fit into the back of the hub. I have not been able to find a reasonably priced replacement rotor. They are considerably more expensive than the average and not very common.

Hey Bob,
Just found this thread while researching disc brake options for my '70 Impala, excellent idea! I have also found the same idea explained elsewhere on line.
I have a couple of questions about this:
Does the Vette set-up put the wheel in the same location in the wheelwell?
Since the Vette and Impala spindles are the same part number, why not keep my stock Impala spindle?
Is the spndle a wear item, should I go for a new one justto be on the safe side?

As far as I can tell without actually measuring, the wheel track remains the same. If the part numbers for the Corvette/Impala spindles are the same, I guess you could use the Impala spindles. I bought the Corvette brakes as an assembly--everything between the upper and lower ball joints. So I just used the Corvette spindles. Spindles aren't an expendable part, so unless there's specific damage you don't need "new" ones.

if memory serves me correcty: vette and impala spindles are the same but not hub and roter, vette roter mounts on the outside of hub. impala mounts on inside of hub therefore u will track 1/4"-7/16 wider on each side if u go with vette roter. i have a 65 impa and put 70 disk brake setup on it . all components mounted like butta. stops on a 25 cent piece, no pullig, verry happy. impa roter and hub still availible new as well as spindle. just gutta do some diggin. hope this helps.........................

Thanks for these infos!
Since budget is an issue for me, I will then keep my Impala spindles... With Corvette rotors, hubs and calipers. I have not been able to find new Impala rotors or very expensive: a few years ago, I found some 2000 miles from me, for $700 the pair!... Future maintenance will be much easier with Corvette parts!
Something else I have learnt is that there is a problem with the stock Corvette calipers corroding, so I will need aftermarket calipers...

Just another question!
If I go with stock Impala spindle and Corvette hub/rotor, which wheel bearings do I use, Impala or Corvette? Or are they the same?
Thanks!
