Frank, You made me go pullout the '50 Olds Custom that I keep threatening to build. I have the pad printed wide whites in the kit, and even though they are in the plastic baggy I'm going to have to redo them anyway. If the ones that Revell sent you are like these they are very close to a wide white of that time line. You mentioned using the Sombrero hub caps, are you thinking of the Merc. kit's Sombreros or the kits '55 Olds. Fiesta caps ? Either would look good. You might consider painting the very small edge of the hub caps that would represent the wheel. I don't build a lot of models with full wheel covers but the ones that I have this little touch seems to give then hub cap a more realistic look to my eye. Look forward to the rest of your build.
Dennis, I noticed from your address you may not be real close to a Michael's. I have used parts that are originally intended for making jewelry. The product that you might look for is made in China so I would think it would be available anywhere that carries jewelry making products. It is called Jump Rings Anillas. They make several different sizes but the one I bought is 0.15 in / 4 mm. They are very thin and almost like a stainless silver color. It could pass for the portals on a model.
Pegasus has a wheel that is just about dead on. Their stock #2305 "Holli's" in chrome, and they have gold also. If you look under the after market section on this site they list all of the major parts suppliers and you can access their web site and look at all of their products. They also have great disc brakes also.
On your white wall issue I think Brett's post is an excellent example of the changing times of white walls. In 1950 most white walls were like the first picture. As time went by white walls got smaller and smaller. By the mid 50's if you bought white walls they would look more like the second picture. By the 60's they were quiet a bit slimmer and about 1961 or 1962 you would see mostly the narrow whites with a black band between the white wall and the rim. This got slimmer and slimmer to a point in the mid 60's you had a white wall no wider than the new red line tires of the day. The size of white wall you use would depend on what time line you were going for with your build. As an aside, besides the changing style of the day, one of the practical reasons for the change was that people would bounce off curbs when parking and really make a mess off the white wall. Used to have to clean my mother's with SOS pads. If you look at the side walls of the 60's you will notice a raised ridge on the side before the start of the white wall. This went a long way to protect the white portion of the side wall.
Brett's idea sounds good, but I would suggest that if you are able to get the decals off in one piece you should scan them so that you could make new decals. This would also give you an extra set of decals that you could use for a team car or any thing else.
I agree with Steven, you should go with black. This would represent a black rubber seal between the body and the clear light cover. Try just a light coat of black from a Sharpie on the edge of the clear plastic. Your model looks great.
Great build and the interior is outstanding. The shifter business, the shifter on O.E.M. consoles usually had an area toward the driver from center where the shifter would come thru the floor. This was because the shift linkage is on the driver side of the transmission. With automatics they are usually cable driven and can be mounted almost anywhere. Since this is a custom interior you can mount the shifter where ever you want.
The top looks great either way, just different styles. A coworker years ago had a Buick from the late '60s with the silver body and vinyl roof and I thought it looked good. I think the maroon roof would look a little more realistic with maybe a light coat of flat or semi- flat clear. Great build either way.
While I'm in the no skirts camp, it may look right if your doing a "full dress" type build. At that time, and depending on what part of the country you lived in, the skirts were almost a default option much like duel exhaust and glass packs. If you have any of the Revell '59 Impala kits I think some of them had bumper guards that you may be able to use. If you are still thinking "full dress" you might think about a continental kit . One last thought on the skirts, maybe the old '57 Mercury cruiser skirts or even the larger "bubble" type skirts if you are going all the way.
The '62s I remember usually had the insert painted white or black. Some were tied to the interior color. If you use a lighter color as an accent in the interior you could also add it to the insert. Just a thought.
