Why not just walk outside and CLUTCH the first exposed neck to cross you unarmored, crushing the disgusting underbreed's esophagus while they gurgle in agony and remorse as their short, pointless excuse for a life flashes before their dry, crustacean eyes. Unless it's a puppy. Don't hurt puppies >

Never seen an auto parts store?!

That shouldn't be hard! Pretty sure any parts store can help you. If not then try e-bay or one of the suppliers for vintage Ford products. If all else fails go to Hemming.com to find some one who specializes in out of date clutches.

Hard to find. My usual go-to sites had nothing. I found this
https://www.cjponyparts.com/mcleod-clutch-kit-rst-twin-disc-157t-flywheel-10in-and-10-1-2in-289-302-1965-1995/p/CK213/

But I don't know if it'll actually fit. It also costs a lot for a clutch kit. You have Borg-Warner SR4 transmission, it was pretty common in mid-70's to early 80's Jeeps, you might be able to see if any jeep clutches cross-reference with your car.

Also you have a Mustang II, Not a Mustang.
