• So I’m probably number 1,000,000 to ask this question.

    I know Marti reports do not start until 1967. I have this car with my serial number but the door tag is also gone. How do I find anymore detail about it? It’s a barn find project that’s got the correct 4 speed in it and wrong engine. So I can assume it was a factory 4 speed. It has the long style gauges so it’s likely std interior. But if I’m going to recreate the door tag how do I find date, axle ratio, etc?

    In regards to scheduled build date, Shelby people use the steering box date code if it is an HCC-AX. It is assumed that the steering box rarely gets changed so is more likely to be more correct. There are also date stampings on a lot of the sheet metal that are part of the welded structure. You can also compare your VIN to other VINs in Tony Gregorys book or the Mustang book done by Jim Smart years ago called "In search of Mustangs" for approximation..

    Axle ratio, if you have the original rear end, is easy. Ford did not offer a locking rear end for a Hipo Mustang in 1965, so that is already a given.

  • Thanks for the pointers. That brings my next question. Were K codes Equa Lok or Traction Lok?

    Mustang did not get the locking rear end on a Hipo 289 until 1966 and it was an Equa Lock. This would explain why Shelby used the DAPCO no spin (Detroit Locker) in 1965. In 1965 the Hipo 289 was the only Mustang that was not available with a locking rear end. The traction lock, with 8 cylinder engines, generally began in the 1968 model year.

  • Sorry for all the questions. I've owned Mustangs since I was 12 when I bought a 65 A code coupe. But nothing I have done has been concours restoration targeted. It's all been restomod of some sort. So this is new to me.

    Is there a good site with pics to show how the bottom of the car should be done and where undercoating goes and doesn't?

    I do not know if this car was a GT or not. The car was wrecked and the rad support is gone to look for a punched hole. It's K so it has the dual exhaust hangers and right rear frame rail block off for the rear hanger. There is no fog light switch but there appears to be holes for it. The car was drag raced and stripped down before becoming a street car again later.

    So my question is if it's non GT, did they all have the rocker molding? I'm not a fan.

  • concoursmustang.com (sp?) has a lot of info. They have a library section that has detailing info. The forum has a wealth of info in topics. The exhaust hangers and rear rail reinforce were for dual exhaust cars -> Check for K pinion snubber on body-for 9" axle.

    Dual exhaust cars, A (GT) and K (all) both had the same pinion snubber and exhaust hangers

  • I thought the 9" axle had a different snubber plate on the unibody-actually the difference is no holes in the plate for the 9" snubber (maybe 65 only- some plants) and the 8" axle is an A code and 9" axle is a K code

    ...can someone confirm....Fred?

    6T09KGT is correct about the unibody snubber plate being the same for an A code GT as any K code. I have also observed cases where Kars recieved both the standard rubber stop that bolts to the body and the rubber stop that mounts to the third member. As you might expect, neither stop does well and both get damaged over the years. My belief is that all Mustangs exept the GT and Hipo received the body mounted stop. As the chassis was coming down the line, the worker can easily miss the very infrequent GT or K that would not get the body mounted version.

  • That snubber looks pretty standard to me. What does the C code cars get if not the one from the yellow GT coupe?

    Also, I asked earlier in the thread, did all non GT cars get the rocker molding? I'm not a fan and would like to omit them.

    In regards to the standard snubber plate, it is more square and appears a little taller. The GT and Hipo plate have a noticeable "smile" in the rear cut out of the metal. Once you have seen it, you cannot "unsee" it.

    I crawled under my C code and the K code and can see the C code metal pad that the rubber is bolted to is more bulbous.

    Also, the correct 9 inch housing for these cars, does it have a ring gear bulge or is the back completely convex?

    Can somebody answer my other question too? I actually have more because I've never worried about being stock correct and just don't know despite owning my first Mustang when I was 12. LOL. Were all non GT cars equipped with rocker molding? How about things like the "FORD" on the hood? Could the hood be plain? I do know the hood front lip chrome was some type of option. I know they all had horses in the grill and the 2+2 emblems. Did all not GTs have the bumperettes too? I'm just more into the less chrome look.

  • Yes, all non-GT cars had rocker molding. Pretty sure all cars had FORD on the hood except Shelby. The trim on the lip on the hood I believe was standard. 2+2 emblems I believe were fastback only, but not on GT's. Rear bumperettes were not on GT's. As mentioned earlier, the Concours Mustang sight has all the answers for details your looking for

  • In regards to the rear end housing with the ring gear bulge, that was NOT done in the 1965 model year. In approximately October of 1965 was the changeover to that type of housing.

  • My VIN is 5T09K153619. The door tag is gone. All I can get from the VIN that I didn't know is it's a Metuchen, NJ car. #53619 at that plant. Anyone have a number very close so I can assess a build date? What is the best panel and location for a date code on the body? How do I know any details of the car to recreate a data tag? Do I technically have carte blanche to pick a color since there are no records? It's all primer now and I can't see any original color on the car.

  • Did you take a hard look up under the dash to see if you can find any traces of original color? I think it would be hard to get rid of all the original color unless the completely bare uni-body has been thoroughly media blasted.

    If there is any color seen under there, scrape it with a small screwdriver to see if a top layer of paint comes off easily, which it might if resprayed with no sanding where its hard to reach. I believe my 65 which is painted Prairie Gold was originally red, based on what I found up under the dash. I could not find any other traces anywhere else on the car. The only place I haven't looked is inside the doors, but doors can always be from a different car.
