66 Convertible date code locations
« on: June 09, 2014, 01:37:10 AM »
I am going to inspect a 66 mustang convertible for a friend tomorrow. She is a 289 toploader 4 speed.

 I did a preliminary inspection the other day and the body is all steel. The paint and underlayment's are about 15 Mils, there is 30 mils on the rear panel where the gas cap is located which I assume is primer.

Where are the date codes located?

Does this car have tags on the intake, transmission and rear end if the car has not been molested?

There is some red oxide visible in the tunnel on the undercarriage and it looks dry with no undercoating.  She was born 6-4-1966 in San Jose.  Other inspection suggestions any of you may have would be greatly appreciated.  Thank you in advance.

If your asking about sheet metal they are on just about 95% of all the sheet metal panels that make up the car. It would take up allot of time just to compile a complete list and their location. I know I've tried

A very very short list for 65-66's off the top of my head

Fenders - fender lip

Inner fender panels - passenger rear - in the center of the panel, Driver rear - on top where the fender bolts on/second Vin location, Drivers front - under the washer bag

Inner fender to firewall/cowl transition - on top of the small panel

Sway bar mounting brackets - facing up to the engine compartment

Rear bumper brackets welded to trunk floor - on top of the piece

Firewall - under the front edge of the passenger side carpet

Floor - depends on the body type. Don't recall the convertible

Doors inner panel (outer panel is dated also) behind the door panel

Each frame rail will have one on the inner and one on the outer surface

Rocker panel - on the bottom surface by pinchweld

Front bumper - drivers side square extension near bumper bracket

Taillight panel - behind the rear valance

Front lower valance - on one of the "ear" that extends up under the front bumper


Some will be right side up some may be reversed. For others stamping locations differ depending on year and even stamping plant

Yes they did

Check everything, do an inventory, check for rust and past damage, A complete inspection should take you 4 or so hours a little more if the car is on the ground

Great Jeff, I had no idea there are stamps on so many components! Thank you.
