Opportunity to buy a 65 Fastback GT K-Code - Questions!!!

If you haven't read this already I highly recommend it. Identify factory GTs It's from KAR Mustang out of Ohio, they continually buy and sell mustangs so they might give you a ballpark of what it's worth. Post some pictures if you have them and the group can help point out some potential problems.

Good luck with the car if you end up buying it.

ALOT of it depends on how "original" he is claiming it is. Anything can happen to a 40 year old car. You can have a true k code car with very little original equipment of you can have an imposter. Alot of stuff can be faked. if he's claiming it all original then some stuff he can't.

The instrument cluster should be round with gauges
All GT's had front disk brakes
I think all 65 GTs were stick
If it has the original carb it should be a 4 barrel Autolite 4100 carb with a Z on the carburetor tag and on the carb base. Even if it doesn't have a carburetor tag you should be able to look at the base. It should also have 1.12 on the side stamped in a circle. (It's not uncommon to find 1.12 carbs, but the engineering numbers should have a Z to indicate it's for a mustang.)

The rear frame rails have holes punched that can't be faked because of the trunk floor being in the way. (This assume he is claiming it's orig)

If it is a true K code, then it would have to be a GT. They only offered the K as a GT.

NOT TRUE! the K code engine was available in the Mustang without being a GT. I had one, and I know plenty were built before the GT option was available mid year. One other thing about the carb, it should be manual choke.

65 GT's can be either stick or automatic.

65 K engined cars will all be sticks. Automatics were available in 66.

All K codes will have a 9" rear axle. Can be an open or even a locker.

There can be either an A code 4bbl engine or a K code HiPo. No other engine combination was offered-so no 2bbls or I6 GT's.

Yes, one does not need to have a GT to get the K engine. That was a seperate option. A GT could be added to any normal body style, coupe, fastback, and convertible. A 65 that is not a GT will have the normal falcon like dash, not the round speedo type similar to a 66--unless the car has pony interior then it will get the round speedo and wood grain trim. GT's do not automatically get a pony interior-that was another option to check on the order sheet.

All the same rules apply to a 66 EXCEPT a 66 would already have the round speedo as it was standard for that year.

A standard K engined car (non-GT) will have some of the features of a GT. Specifically a fast ratio steering box and heavy duty springs which were part of the HiPo package. I am not sure if a heavier sway bar was included, but I would believe so.

There are several ways used to ID a true GT. The link mentioned above will help. All the things must be present for it to be authentic. There should be no chrome in the sculptered area of the quarter panel. Probably the best indicator, as mentioned above, is that the frame rails on both sides have special reinforced holes to mount the tailpipe hangers, although a normal non GT K code "might" have them too due to it also haveing factory dual exhaust. I've never verified this.

The 9" K code axle tubes should be tapered on the ends where the springs attach.
