Hi all, new here, I installed the XV SubFrame connectors on my 69 charger, there was some grinding to do and had to press the floor pan down before welding for a good fit, but I expected that in a 40 year old car. My car's drivers side was the worse fit, as someone had used a jack on that side. I have install pics at

I update the site a lot and right now I am installed the front and rear level II units with brakes from XV, hope it helps!
