69 Barracuda A body 4" PCD Rotors to 4.5" PCD - 73 Dart/Duster Discs?

Hello everyone.

I have a UK spec 69 Barracuda. It runs original Kelsey-Hayes 11.04" Discs on the front, or rotors as the Americans call them. They have the small bolt pattern - 4" PCD. I want 4.5" to fit cragars.

I have it on good advice that 66-69 B body Bendix discs will fit straight on, though they are are very slightly larger at 11.19" diameter. There is appearently enough clearance in my calipers to accommodate the small differnce. The Bendix discs fit like they were made to be there, and have the 4.5" pcd...

Trouble is, these discs are rare, and new ones expensive.

SO - does anyone have any used ones they could ship to the uk, if so how much?

OR do A-body Duster/dart etc discs from '73 onwards fit my car? These are easy to get, but I don't know the size and whether they'll take my existing calipers.

Can anyone help? Does anyone know?  

Best bet is to swap over to the 1973 and newer brakes since that will give both the less expensive rotors and calipers as well as the larger bolt pattern.
