Sorry it's taken so long to wrap this up. Here's the denouement. I re-routed the cable from Kirkham's near center of the car location to one just to the right (as you sit in the car!) of the puke tank. This seems to take the route of the least bends and widest radii. I then ordered a custom hard case cable from the guy recommended by Autometer, maker of my speedo. His name is Roger, Speedometer Services, Milwaukee, 414-463-6660. It would have been cheaper to get a stock speedo from one of the Mustang or Ford parts purveyor, but I got a cable, hardened case, and built to my specs. Roger knows these cables and tranny setups very well. I'm really pleased with the fit, tho' I haven't had a chance to try it out. (see my posts about
oil leaks I'm chasing on the FE section of CC) Thanx for all of your help.

BTW: Roger at the Speedo shop totally "poo-pooed" any belief of some cables being wound opposite the others. The "reverser" sold by many (mine's from Autometer) is, of course, required for the reverse sweep speedo of our cars. steve
