I'm in the process of shopping for some 17" wheels for my 67 galaxie. I have front disk (brake swap conversion 72 t-bird donor) and drum in the rear. I want to put some 17x8 front and rear. What kind of backspacing am I looking at. I've looked through the threads and can't find any info. Can anyone help? Or if anyone has any for sale let me know. Thanks in advance everyone.
