I have now seen 4 sources for adjustable strut rods for 65-66's. We all know about TCP ($400) and Global West ($300). They both seem like bolt-in installations. There are also two similar ones I have seen that look like they require a slight modification to the front strut mounting point. Once is from Cobra Automotive in New England and the other I caught from a previous post was from Delta Bay. They both run around $200 and may actually be the same unit. Has anyone installed either of these? What is the modification necessary? I thought BillGear replied once on the Cobra Automotive unit, but I don't think he mentioned the modification. Any insight is appreciated. Thanks.
