Turn the rotors.

Rock Auto had them last time I looked. The problem with these rotors is they don't have a lot of meat — most originals have already been turned to the max.

Yeah that’s my concern as well.
I’ll check Rock Auto

You have to pay close attention to which ones you get. The rotor hats on some are angled such that they rub the caliper piston dust boots.

Stock minimum thickness is .790". Just check them first, if turntable I recommend that. Some replacement ones have issues with the hat being to wide and hence rubs a hole in dust seals allowing debris to get at the pistons….

If they are junk I’d try the power stops. Rock auto also sells dynamic friction for pretty cheap

Chk Summit they have/had them. I know Centric was one and maybe Raybestos the other one?
Like Rusty said they may need to be turned down to avoid dust boot rubbing.

Originally, new OEM Mopar rotors have a thickness of .810. According to most sources, you could turn stock rotors to .790 and discard them at .780. I've turned them much thinner (even down to .750 without an issue, but, trying to find a machine shop that will do it, might not be easy due to liability issues.

I can’t say enough about the Power Stop rotors.
Replaced mine not long ago with Dorman and they both warped within a month.
6 months in with the Power Stops and straight as an arrow.
Plus the drilled and slotted is nice for better cooling.

Oops. Typo brain fart. Yes 790 is the number I knew as a min thickness
Don’t know why I said 750, long day yesterday…
And now upon a deeper dive and to just make sure I am also seeing .810 in the 70 Plymouth service manual…

Good to hear as that’s what I’ve purchased
Thanks
