I am building a tube framed, project car, using Mustang wheels and spindles.
My question.
What Mustang model might have used a rear caliper with 1 to 1.5 " pistons?

I need a replacement caliper for a very light car. My current IRS is from a Lincoln Mark and the stock calipers are way to large.

Does anyone have any usable, stock, calipers with the above size for sale?

Have you upgraded your Mustang and now have stock parts lying about collecting dust?

Thanks in advance
Paul
