Hahaha, we are on a crusade about the axle! The prestige issue is a really great kit with a lot of extra stuff. The next release of the '63 convertible was missing the removable hardtop and wheelcovers. Probably other stuff too. Remember, at $15 in 1987, this kit was 2X more expensive the usual AMT kits. Despite how good the kit is, they can be found cheap on eBay. That is good for the builders, not the collectors.
This Mustang was originally a '70 Mustang by Palmer Scale Models. It got updated like the Challenger did. The plain chassis is really a copy of the AMT '69 Mustang annual kit. AMT designed that kit chassis like a promo; 1 piece. It's amazing how well Palmer copied the AMT. If you ever find a Palmer '70 Mustang, buy it. It makes a decent beginning to a Boss 302/429 in 1/25 scale. The other Bosses are the '70 MPC and '70 Monogram/Revell. The Mustang, Challenger and Corvette are the only 1/25 Palmer kits ever made. Not to be confused with those other horrible 1/32? multi-piece caricatures that box tops promised cars that could not be delivered in the box.
T408 Street Shaker had chromed reversed baby moons in place of the chromed mags. The mags were un-chromed with the other body parts. T408s chrome set was pretty bare except it did have the display disc brake and fire extinguisher.
Wally, if it is the AMT body (not MPC) and it is a '63 with a backup light in the center, it must be the early Street Rods issue. Mine was molded in white plastic though, not black. Most early A163 box tops state 25th anniversary on the left with Street Rods on the right. Only the 1973-74 kits had advertising on the box bottom, something else that differentiates early 163 boxes from late ones. The reason early A163s have a center back up light on a 1963 body is because AMT converted it from the last version, a 1967. It is not clear to me when AMT figured out the mistake. I would be curious if any 63s from Lesney or ERTL had this mistake. Can you post a photo of the body with the incorrect backup light?
The Prestige Corvette kit has a lot of good parts. I believe the TV camera was part of a parts pack AMT used to sell. It is worth buying for the wheel covers and 2 extra tops. Last of the whitewall tires from ERTL, though some are mis-printed.
