All,
Thanks for the responses. Info as follows:
1. The rim is catching on the edge of the brake caliper (just behind the bleed nipple).
2. All four wheels are fine on the other 3 hubs, only touches on the LHF caliper.
3. All four wheels rub on the LHF - it barely catches but you can hear the scrape and see a small rub all around the wheel.
4. Brakes are original standard discs.
5. I have spoken with Image Restorations and they have used the same wheels on other Mustangs with no issues.
Cheers
Gavin
