DOES THE HDK SUSPENSION K-MEMBER HANDLE BETTER THAN A T-BAR SUSPENSION?

Bat them. In the tight spot, roll a bat between the tire and the fender. Good to use a heat gun to soften the paint a bit to prevent cracking.

I' guessing you are referring to the top of the fender.

The problem comes into play at the lower front part of the fender when turning in or out.
Seems to be a problem for 67-69 Cudas only.

Here's what one of our members did to get required clearance for 18" tires on a Cuda.
