Well, there’s a major difference in the sheet metal shape, of course. So it would necessarily cause a little headache, but I’m not sure just how much trouble it would cause for mounting panels.
Maybe there’s a simple filler material (wood, metal, plastic, fiberglass?) you could use.
And if you’re using carpet over the floor, you could match the carpet over your new panel section.
If you’re going to buy them anyway, I guess you will find out!
I have some pictures somewhere around here of 77 inner quarter panels around the wheel well, but it might take me longer to find them, and for you to do the work!
Good luck!
