In one of my car magazines, there is a father and son hopping up Fairmont wagons. I think one with a 351 was silver, and the second one was chocolate with a 302 and it was faster on the road track. In the second one, they used an SVO front K member and a Cobra IRS. Is there any real differences in geometry in the SVO K member vs. the later V-8 Mustang part? If so, what?
