That link didn't work for me, but if it's another yellow on yellow Z/28, I've now learned of at least 7-8 of them and I am sure there are plenty more. The option list on this one does make it pretty unique though. That being said, I have yet to find another yellow Z with the liquid tire chain option?
I was out to check out the progress and looked at the doors today. The driver's door had a dent at the front edge that Ron uncovered and pulled before fixing a couple of other spots & applying epoxy to the inner seams. He'll finish the doors and get them into primer along with the inside of the car before it goes onto the rotisserie.
