  1. The shop manual for the M-6 transmission has several diagrams of the wiring circuit, showing which circuits are live for which function. The power comes from the ignition switch. The governor and the kick-down switch ground the circuit under certain conditions. The power winds up operating the solenoid, to dump the internal oil pressure and effect a shift. Follow the wiring diagrams. For your 12-volt system, you have positive power and negative ground. So two questions, and maybe the guys can chip in: 1) Will the negative ground affect the function of the solenoid, pulling when it should push, or is the action all the same regardless of ground? 2) Will the 12-volt circuit be too much for the solenoid, requiring a resistor or runtz?
  2. Deja Vu. We discussed this in another thread. Steering wheel off. Good. The steering column is perpetually wed to the steering gearbox. Remove the column and box from below, or raise the body high enough to clear the top of the column.
  3. I suppose that when the cars were assembled, the shaft and column cover were attached to the steering box and the frame, with the shifting shaft attached at the bottom to the transmission linkage. The body would be dropped onto the frame with the steering shaft going through the hole in the cowl at the sloping part of the floor. Then the steering wheel and shift lever would be installed. So, if you are removing the body, you can do the reverse. Or just pull the entire column, and steering box, less steering wheel and shift lever, out the bottom (if the vehicle is high enough off the floor). Just my WAG. New thought: In assembly, with the floor panel removed, would the body be dropped over the entire steering assembly, with wheel, and the floor panel put in later? Which is easier - install the steering wheel and shift lever later, or install the floor panel and carpeting or mat later? Pennies per unit were at stake. No, pedals in the way. Anybody know what happened during the body drop?
  4. The wiring is different between the M5 and the M6.
  5. The "column" consists of the central shaft and the external jacket. The shaft is permanently connected to the steering gear box. You can remove the steering wheel and the external jacket, and then you are left with the shaft. You then drop the gearbox and shaft as a unit.
  6. I just love the long wheelbase cars, probably because my dad had, in succession, a 47 DeSoto Suburban, a 50 DeSoto Suburban, and a Cadillac Series 75. (He got tired of the six cylinder boats with the fluid drive, and went with the V8 Caddie with the Hydromatic, and the early tail fins.) After his two oldest daughters got married, my dad went to regular sedans.
  7. Walt, I remembered what you told me about the DeVal. The DeVal was news to most of the guys. Good to see photos above of the actual red monster and its versatile accessories. Good old Yankee ingenuity.
  8. Where have I heard of a DeVal engine in a D-24 Business coupe? Suddenly it's all coming back to me. A Motown guy came to visit me in 2016. His business coupe had a DeVal engine! Teaser Photo:
  9. Is that strap holding the fender up or the hood down? Or both?
  10. Hey, guys, someday I'll be a PO. But I think I've kept track of my work, and there will be plenty of digital photos of the work. I wrote a small book about my power steering project. But I'm sure there will still be something to mystify the next owner.
  11. Trying to figure out a permanent strap, I might take half-inch EMT (electrical metallic tubing) and flatten the ends and bend them over. I might want some way to adjust the effective length. Something threaded, that would pull the fender in. . Time for some enginuity? ingenuity: (the quality of being clever, original, and inventive).
  12. There's supposed to be a strap to pull the bottom of the front fender, at the rear of the wheel opening, closer to the frame. Here are a before and after, with a view of a turnbuckle to pull the fender edge inward. The turnbuckle is temporary, until I fabricate a less elaborate strap.
  13. Uncle Sam wanted a continual supply of engines for their aircraft tugs, so when Ma Mopar discontinued the block, DeVal made the engines under license from Chrysler. Some of the casting plugs are different, but the important stuff meets spec.
  14. Speaking of girls at the controls: Grand daughter Paxton's solo flight. Flying lessons Spring and Summer, Purdue in the Fall, for aviation technology. Same ear-to-ear smile that my kids and grand kids had, before driving age, after taking a spin through the local cemetery, under adult supervision, of course. Paxton was on her own, but in radio communication with the instructor.
  15. The car has a crooked smile. The bumper is bent, and the left fender is higher than the right.
