Thanks. Yeah that is the Nova Kevin owns now. Not sure what year he aquired it but I built the model back in 1990. I've had 'em a long time. I've got a couple more I'm going to touch up before I sell them as they are just as old and have a few more battle wounds and one or two that I didn't detail as well back then.
I've got no clue which kit I got the hubcaps from but they were the closest thing I could find to the 69 hubcaps back then. Nowadays there are companies that offer Resin parts and make the exact hubcaps. Modelhaus is one of em.
