See my other thread about what the interchange manuals say. I also went to a bendix and a wagner site and verified the burb rotors will fit. (provided their applications are correct) I looked up the rotors for a 71 C/10 and up to a 91 Burb. same part numbers.
Crossreference Thread for Rotors
I emailed powerslot today as well, I'll see what they say.
Bigger is better for both rotors and calipers. Its mostly opinion with some valid points and theories on the drilled and sloted rotors of the OE size. I guess if I'm gonna buy new, and not spend thousands on a Baer kit, I will throw a few extra bucks and get the drilled / slotted / cadmium plated ones.
I bought some rotors off eBay for my Mazda (read: commuter car) from user ID " raceconcepts" they worked great and were silver cadmium plated and dont rust. always look shiny. a nice plus. He said he can get them our trucks for $130 plus shipping.
Baer would be my choice if I had the cash.
SSB - Never again. I bought a rear disc conversion for an S-10 I had a few years ago. nothing but problems!
never hear of the others ...
Can anyone compare that price to what they have found?
