80's Mustang Dog House/Arrestor

The box itself is almost assuredly the same- and that same box was used from ‘70 through ‘82 on several models including both the 16’5” (skier/mustang/ski tique) and 18’9” 2001. It’s possible that there are slight variations in floor vs engine mount height due to various model, stringer, cradle variations etc… but the long and the short of it is that no stock engine (302/351w/305/350) should have been so tight on clearance that a “low profile” (presumably meaning 2” tall?) arrestor was needed. Many had 3-4” tall arrestors.
