I would go with Mark's suggestion since the original kits windshield frame wasn't all that special anyway. Remember the original AMT '32 five window kit dates to the early '60's. This kit was as good as it gets at that time though.
All of those bits and pieces going thru the engine can cause more damage than you can imagine. Think about a very small bit of the Turbo Blades as they pass thru the Intake manifold, passages in the heads to the intake valves to bouncing between the pistons and the heads in the combustion chamber and what ever is left or new bits it may pickup on it's way thru the exhaust valves. I would consider a good examination of the block for any unseen damage to the cylinder walls as well. This may cost you a lot of your lunch money for a while.
Thanks for the memories. In '69 and part of '70 I worked for Union Oil Company at the Colton Distribution Center in near by Colton Ca. and one of my duties was to work some of the race weekends at Riverside Raceway. After the teams would load up their gas cans we could get on top of the Union Oil tanker truck and see sections of the track during a race. The most enjoyable part for myself was during the practice sessions days before the NASCAR races. Union Oil had a mock service station where we would give the teams their gas and we were at the end of the garage area. We would take turns wondering thru the garages, and had to makes sure we didn't get in their way, and see the race cars up close.
Great job making this into a convertible . The colors with the interior and the stacked folded top give the appearance of something costing far more than a Studebaker, The Hudson style A pillar looks like a style they may have used in that era. Using the wire wheels with thin white walls look in keeping with a highline car. All of the finishes and the added trim moldings give your build a very OEM look.
Great looking "Black & White" . From the photos it looks as if you have a sharp line between the colors. I did an Oldsmobile once and chased the colors back and forth on the door lines.
I think I recall the 1990's AMT NASCAR kits had a dry sump oiling on the kits engines. The system was pretty basic but with some detailing you could make it look pretty good.
I can cover your 11 '57 Chevys and raise you just as many '66 Impalas and even more '86 Monte Carlo SS and I don't know how many '72 Nova SS are in the basement. Sounds like you're not alone with the problem either.
Great looking "Movie Car Build". The paint job looks even better than the movie car did, but the stance and trim look perfect. You have to wonder how many Mustangs and Chargers were sold based on viewers of that movie.
Great looking paint, perfect looking stance and the wheels look great on this redo. This, to me anyway, is the best looking model that the Cougar ever offered. I had a friend who had a dark green XR-7 with the saddle beige interior back when, always liked that car.
Beautiful looking restoration and the color looks like one of the popular colors that Pontiac had at the time. The original builder seems to have used all of the options from the original kit.
I agree with your solution for the grill. As mentioned by others it does give it a more finished look. The only thing I might suggest considering, and this is just a personal touch, think about how the hood would look with the front edges of the hood where it meets the grill and front fender being rounded.
I also purchased a unit just like David G's at a local hobby shop. I have had it for several years and would think it would be something that would work for you. While some of the booth parts a made of plastic, they do fold down for storage. What ever you use be sure that the unit is well vented to the outside and change the filter often. Beyond that I haven't had any issues with my unit in years. You will want to setup some sort of additional lighting depending on where you use it.
Being retired has given me the chance to put in a little more time. I will usually work on one model at a time and a couple of hours a day. We just moved and I'm still in the unpacking stage so I haven't been able to work on anything for almost a month. I hope to have a room in the basement converted into an office as I had before, but that will take a month or so.
