Welcome. If you can get a few photos of the IFS from several different angles with the wheels off, I bet we can ID it. As Mark mentioned in his post the Pacer clip was the “preferred” way to clip your frame style until the Pacer supply dried up. Camero, Firebird, Nova clips took over after that. Great project to share with family. I sold my chopped and heavily modified ‘48 Suburban a few years ago to a Grandfather in Alabama who wanted to take his grandkids on Cruising the Coast.
