Looking at two of my factory 14" rally wheels, I see I have one JJ and one JK. The difference seems to be that the JJ is 4" back spacing and the JK is 4-3/8" back spacing. Both are clear for disc brakes. I need to unpack my other rims and see what they are. My question then, if I have 2 of each style, should those go on the front or rear? Does it matter other than looks and not hitting the fender lip?
In 1967, you should have JK all around with 4 1/2" back spacing.I bet you need more back space on the rear, so I would use the JK's on the rear.
Upon further investigation, I had 4 JK's and only one JJ. The JJ has a deeper dish, so that would be a smaller backspace. Set it aside. Ran down to the local tire empire used tire store and got 4 tires, mounted and balanced. Hankook white walls even. 205/70 r14 $200 Guess I have a matching set to use for setting up everything. The mis-matched stuff that is on there can go on a shelf.
