And don't forget the sacrificial aluminum head
If you like, I can measure the cap on my '65 Mustang 289.
Robin,
Sorry to take so long to get back to you on this.
The cap on the Mustang is a SMCO 14
The disk at the bottom of the spring measures 1.525"
Distance from the disk to the raised ring inside the cap is .8"
Distance between the tabs on the cap is 2.045"
Cap diameter is 2.34"
Distance from the disk to the raised ring inside the cap with the spring compressed .656"
The color of the spring is green.
Radiator neck is .798" deep.
Inside Diameter is 1.6"
Outside Diameter is 2.21"
And two other neck measurements that I don't recall where or what I measured
Flange .21
At tabs 1.95
Sorry if you have to convert these measurements, didn't think about that.
Also this was measured with my CHEAP Harbour Freight digital caliper.

Hi Robin

Cost about 7 bucks

Hi Robin
Re Radiator cap, not sure of the brand just went in and the guy gave me one that suted an early model ford 289. i note you have mentioned sacrificial anode ( which mine has not got) and i have alloy heads & alloy radiator. Does that mean that the sacrificial anode has to be inferior alloy as compared to the heads and the radiator ? Also what type of radiator fluid do u use for this type of engine ?
Regards
Allan
