65 Barracuda Wheel size help

Hi all,

I have a 65 Barracuda 273 with drum all round. Stock standard undercarriage and suspension. I want to get a set of the "60's racer" style Torque thrusts.

I'm inclined to go 14" as they are period correct, but may go 15" as the tyres are easier to source.

What I would like to know is, what width rim and rubber can you fit on a 65 Barracuda without fouling on the fenders, leaf springs or wheel arches.
