Dr Diff rear disc conversion

Any chance a 14" ralley will fit over that, I see in most kits they require a 15" wheel minimum?

From his website...

Unlike most other kits, this super-clean version works with OEM adjustable/tapered wheel bearings as well as Green ball wheel bearings. It also clears 14" and larger Mopar spec wheels (including 14" and 15" Magnum and Rally wheels).
