69' outer wheel house?

So I’m in need of outer wheelhouses for both my 1/4s. The only repros I can find are for 67-68. So is there another work around to replace the 69 outers? Really think I can get away with just the back parts behind the tires, so is it possible to use a 69 mustang wheelhouse and cut off what I need?

I believe John has a pair for 69.
