C5 or C4 disc??

[Steve68]

This got deleted on the shut down on Friday:

I have a set of disc I think there C4 13" this is a number thats on them
BPC 494 0322 2223P, Someone who works in the parts field ID these before, can someone lend some assistance again,

I thought they were 13" C5 but I have a used set of those rotor and they aren't the same, different,

so the C4's 13" 1.11" width with a hat backspacing of 1 7/8
and the C5 are 13" 1.26" width with a hat B/S of 1 1/2
These are the measurements I have come up with,

I did a search and didn't come up with much or my old post,

Thanks Steve

OK then, does anybody have a pic of the C4 rotor with a C5 caliper, thats supposed to be the hot swap, anybody? Bueller?

Here are a couple Steve. Not the best pics in the world, but C5 calipers w/C4 rotors nonetheless.

Thanks Dan, I think I have the same, do you have any shots looking straight at it or a angle shot? I'm trying to see the hat part of the rotor, Thanks again, Steve

Steve, I have a few others that show the drum hub mated with the rotor. I'm going to be pulling the rotors soon to paint them (rusting), so I can take some add'l shots then if you like.

Thanks Dan the 3rd pic is what I was looking for, and the BPC codes are close on the rotors, the 13" C4 has a addition to the hat, it adds a little metal, compared to the C5, Now to order the brackets, who did you get some from? Thank Steve

Sorry that 4th link was broken. Here it is:

I bought the entire kit from Touring-Classics (http://www.touring-classics.com), but they sell the front caliper brackets separately as well. Tell them I sent you!

Steve,
Check out this site...

Lots of good pics and info.
I just ordered my C4 brackets and bolts from them and paid over 50 bucks less (including shipping) then just the cost of the brackets through my local Chevy dealer... Pretty good deal if you ask me...
