I am wondering if anybody has had any luck with tracking down the Wagner brake rotors BD60230 that supposedly is the part# that is correct for 1970-72 Challenger? THey are listed out of stock and unavailable everywhere...are these the correct ones for my T/A? thanks, Marty in Tallahassee (FLpenguin)

You might put some request ads in your local CL.

If you don't have to have the Wagner rotors, Rockauto lists several other options, in stock.

They were plentiful a few years ago, now hard to find. Sometimes you might find Raybestos part#7008R. Rotors for T/A and other Challenger models with disc is same. If it can stop a 440 it can stop a 340-6. A bit spendy tho. I have seen OReillys carry the rotor with their part# 7008RGS. I happen to believe that they use Raybestos parts with their product line. They are $153 ea.
A guy had the same problem finding rotors for his Challenger R/T and ended up getting the Centric ones at Rockauto. He was pretty impressed with fit and finish.
Those were about $53 ea. So you have a couple options there.
Some have used the 73 up rotors and used sleeves to accommodate the inner bearing difference (Dr Diff). Rockauto has the WAGNER BD60463 for $37.

I assume the TA had the same 2 piece original rotor as the 70B body. So any after market while will work will not be OEM correct. I put the rock auto on my 70RR to save the thin 2 piece originals on the car.
