Your Buick modified stocker looks great, well done. I really like what you did with the exhaust. Looks like a car of that era, ready to head to the track.
For me, I like the kit tires. I well remember race cars of that era running those oversized (by today's standard) racing tires. Everyone called them "humpers". Even up to the 80's, NDRA teams were still using them for stagger.
