67-69 BARRACUDA FASTBACK W MINI TUB QUESTION

I mini tubbed my 64 barracuda, very similar.

Retain all your inner structure on the wheel wells when you move them against the frame rail, Re attach the interior panel and then make a spacer to go between that panel and the quarter panel mounting, You can lower where the filler panel meets the inner panel to create a more contoured factory look,that is what I did.
Sorry,I do not have any pictures.
