I know that a late model mustang 17" wheel wont work on the front of a 68 Mustang without spacers because it hits the upper ball joint, but will an 18" clear the ball joint. There are so many wheels on ebay in 18" that look really good and i thought that this might be an alternative...I know the wheels will probably tuck under, but I plan on maybe using air bags, so thants kinda what I am going for...
