A Body Disc Brake Swap 101

Just add a little to this thread. I just upgraded a 68 GTS to the 73 and up disc system. I had some 14in stock steel wheels from a 68 Satellite project with big bolt pattern sitting around. I was just going to use these wheels as rollers until I get the Cragars for it.I found out that these wheels hit the calipers before they are tight on the hub. Sooo... I'm assuming one would have to use different offset 14's or go to 15 in wheels.
Anyone else run into this issue ??? Again... Just a PSA
