I did this exact conversion just this year, used the MPC GTO funny car body. Which is a stock promo body & used the MPC 1972 GTO for chassis & interior. Not a perfect copy of an original '69 kit but close enough & it looks great.
First just about all the info you need are on the two flyers posted above. The toy show is open 9-2, $7 admission, the NNL is open 10-4, $10 admission. There is lots of free parking a couple hundred feet from the door. For your $10 admission you may bring in as few or as many models as you wish. Also we do not have a web site but we do have a Facebook page, search NNL Nationals. If anyone has any more questions please post them here or on the Facebook page. I will be checking both every couple days & will try to answer as many as possible. There is also a partial hotel list on the Facebook page.

SC Miller was one of if not the first to do home casting of model cars. I believe he used polyester resin instead of the now common polyurethane resin. As was said above his stuff was all one piece mold slush cast. He did a lot of interesting subjects. He died a number of years ago. Even if not to build his models were an interesting part of model car history.
I have built a couple of his kits, he does not chrome the bumpers & grills. You will have to use Al Clad or send them out to one of the chrome plating companies. It is not perfect but if you want a Lark it is the only game in town. As any kit plastic or resin with a little time & effort a nice model can be built.
I have built the MCW Studebaker Lark. It is based on the old Jo Han promo. It is a bit larger than 1/25 scale, maybe 1/22 or so. I opened the hood & made a full detail model out of it. Modified a '41 Plymouth flat six the replicate the Stude flat six.
