Hi there, I got this info from the mustang forum by using Google to search for
--mustang convertible/luggage space--
OK-- 2 of the 26x16x12's will not fit.
The problem is the truck (boot) is not square/rectangualar. It curves at the sides because of wheels.
I was able to fit 1- 28x18x11 sideways and 1- 22x14x10 lengthways and it was tight but fit good....
