Factory Torsion Bar Diameter for '65 Formula S?

65 A body torsion bars, generally:
.83 slant six
.85 standard 273 V8
.87 Formula S and anything else with rally suspension

I'm sure there were exceptions, but every one I've ever dealt with had one of the three bars above.

I put .87s in my slant six Valiant, .89s in my 65 Barracuda 340, and .960s in my 67 Barracuda 360. Most on here think any of those bars are too wimpy, and want to run bars larger than one inch. Never tried that myself.
