? about not running inner fenders

[67Fleet]

Figured this would be the best place to ask.....
I'm getting ready to bag my 67 and I'm concerned that I will have to at least notch out my inner fenders for tire clearance. My wheels are offset enough to clear the inside of the outer fender now, but there are already scrub marks from where the tire has hit the inner fender on bigger bumps. As it is now I'm static at 5" lower up front and I've only got about 2" of room before the tire hits. I can either notch out the inner fender or remove them completely, but if I remove them completely what will that due to the structural integrity of the front clip? Will I have to do a lot of fabwork to get it all to work? It looks like the inners are a good part of the support system for the fenders and the core support.

Edit: I've got drop spindles and front disc conversion (not sure what brand as the PO did it), and running 5.25" backspacing on 20" wheels.
