Beautiful work. I have had this kit in my stash since 1994, still unopened. I hope to up my modeling skills significantly before I tackle it (been saying that for the last 20 years). Thanks for the in-depth post.
I believe that those are the correct hubcaps for '59....I built that Skip's version back in the 80's as well and it had the Olds hubcaps....years ago picked up a set of the correct hubcaps and have yet to install them. And indeed the OP's model is very nice....love the color combo. I did the same thing back in the '60's when I first built this kit....couldn't get it right back then so I burned it LOL!
