They're discontinued as of last summer from what I understand. I have them on my 68, and put them on my 00 for a few weeks. If stock GT rims would clear Cobra brake calipers I'm sure the 454's would. The 454's actually off set out a little too far for my GT - meaning they stuck out the front about .5 of an inch so I'm sure they'd give more caliper clearance. pm me you e-mail address for tons of pics of my 00 w/ them on.
