Completed tear down for front end rebuild on the '70 stage 1. Both spindles sitting on the bench. I just noticed they are different. Which one looks correct? What is the other one from? ou:
The Rotors are different. The one on the Right looks like it need to be replaced anyway as the outside surface looks mighty thin. Replacement rorot will probably look like the one on the left. To tell the truth the one on the left looks like its thin on the inboard side. Did you Mic them ?? I don't know if its a opticle illusion or what .
One is a two piece like the old style and the other is the one piece new style. They are functionally identical and I have one of each on my 70 Stage 1 car too. Unless you are going for originality, the one piece is what you will get as a replacement from most places.
The one on the right is probably the original rotor, it's what you call a 2 piece rotor. They were mostly all replaced with the second style. Recently, they started repro-ing the 2 piece rotor, they are available again. I guess it's pick the shape of your Chinesium you like best!
Brand new Delco rotors are available on Amazon.com for about $50 each. I bought 2 back in March for $40 each. No idea why the sudden jump in price.
