Here is a link that lists cars that use a 11" for the 10 spline, a parts store should be able to get you one.

I would be skeptical of that listing at Summit. It says 1 3/8" input shaft, thats a truck trans input size. The T10 should be  1" if I recall correctly.

OPPs, that was for a top loader.

If you have an 11" my recommendation would be a diaphragm clutch rather than a long type. Less pedal pressure in my experience. Before I went to the large input toploader I had an 11" diaphragm clutch for a 390 Ford Pick Up. Worked great and less pedal pressure than the long clutch I had before.

I'm running an 11" diaphragm type LuK clutch assembly in my '57 with a T-85 O.D. (10 spline 1 "). It was listed for a '62 406. Light pedal, no slip and reasonably priced.

"FREE SAMPLE"

My T85 came out of a 1961 390/401hp and has a 23 spline 1"  input. 
Edit: corrected

T 85 maindrives cars (not trucks) in overdrive or straight 3 speeds.... As far as I have seen & rebuilt & according to my B/W factory parts book are all 1" x 23 spline & 1" x 10 spline. Most 1956 & 57 Fords / Mercs were the 1" x 10 spline. 1958 to 62 were 1" x 23 spline. Gear tooth count on maindrives are the same 19t. so they interchange.

For a throw out bearing there are many that will fit depending on the style of pressure plate you use. I have many different depths and they all fit the same fork. Pain in the butt, but I bought what I thought was right the first time, put it on the pivot ball, slid on the t.o. bearing and slid in the trans. The end of the fork was not where I wanted it. Took in back apart, bought one with approximately a 3/8" added collar, put all bactogether and it was right where I wanted it for the linkage. Good luck.
