I purchased this for a 1967 XR7. I had to drill and cut wholes the firewall side to allow some hoses to run through. Then I spent hours cutting and grinding to accommodate for some bump outs on the firewall. Once the hours or fabricating were done, it fit like it was suppose to. This part took a bit of work to get the bolts to fit through the export and the firewall lip. All in all... it fit and feels far more stable and secure.
