I'm thinking of picking up a set,what are youre thoughts on these? are they hoakey or a good idea to run these?
Thanks!

I used a set on a '66 Charger that we drove quote a bit. We took a few long trips (15 hours straight through) with that car using those parts. The newer style 11.75" one piece rotor is 100x better than the 70-72 2-piece rotor, especially if you plan on putting some heat in them.

Fifty bucks compared to replacing spindle/knuckles? Heck yeah.

If your referring to the inner bearing race sleeves for the 1 pc 73 and up rotors for use on the pre 73 spindles, utilizing the smaller 72 and down inner bearing, they will work just fine, if installed properly, I've turned my own down on a lathe many years ago to do this conversion...

You better check with Cass/DrDiff IIRC I don't think he makes those anymore, I could be mistaken?

They're still on his website.

They look just like Speedy Sleeves, that was the name I know them by. Used them all the time, they will work just fine.

I ain't used any of the Docs' items but from the flawless feedback regarding him I would not have a problem on that if/when the time comes.

Yeah that was my thoughts but asked before I pulled the trigger. and I pulled it.

Agreed, there used to be a commercial in my teens that said investigate before you invest and a guy (on here) has a sig that states: common sense, the least common of all the senses. I like that one.
