JL8 Front Brakes

[SS454]

I was woundering on the front JL8 brakes what is diff? I know the calipers and the brakets are but what eles? Also I have seen some people on ebay selling rear JL8 disc caliper brakets but they look like corvette brakets . Is there any diff other than maybe part # or are they the same? They want $350.00 for what is said to be JL8 stuff but the corvette ones go for around $65.00 to $100.00.
Was thinking of put JL8 brakes on my Camaro Just beause I have to get front brakes anyway so thought would look better and work better.
Thanks
