Installing a 42-48 crab dizzy

I found your build thread on the HAMB, in this picture there are two vacuum ports on the drivers side of your Edmunds intake.

As stated by big deuce, the vacuum port is on the adaptor, and that square boss is the one that needs attention to be sure it clears and sits flat. Can you not rig up a temporary rubber line for the experiment?
 
Keep us posted with your progress, I really enjoyed going through the build thread on the HAMB, that '40 is really taking shape!
 
If the VW is 12v and the bosch is blue, it's an excellent coil and has internal resistor. Plug n play. That condensor is my favorite go to. It's a 'nippondenso' spec'd for an early toyota landcruiser. I had been remounting condensors up at the coil for easy access as I had experienced a few failures (napa part) on the road and was sick of dealing with under the belts location for a condensor swap. Rubber, or better yet, silicone vacuum tubing is perfect forn this stage of your experiment. I just leave an inch of the tiny copper tubing past the nut.
 
Ok dumb question. What connects to the negative side of the coil? The condenser? I’m getting it all installed today.
 
on most cars, power, whether 6v or 12v, runs from one of the battery terminals to the positive post on the coil, through the coil and out the negative terminal, and from there to the small connector on the distributor. then, through the points to ground via the distributor's housing. a secondary path to ground, usually internal or in close proximity to the distributor, is provided by a parallel circuit that involves the condenser. the points circuit and the condenser circuits run in parallel and together serve to insure long term use of the points. how that is accomplished is murky and finding a straightforward answer to it has eluded me for a few years now.

key word being "straightforward". :)

Remember, if pos earth car the power lead goes to the negative side of the coil and the pos coil goes to the points . IIrc.

I will emphasize that these Fords are all positive ground from the factory. Therefore, this explanation, while correct for most later model cars made by other manufacturers, is backwards for Fords. Luckily, it is impossible to install an early Ford coil backwards because of their construction. On the later models, it is the wire from the ignition to the negative side of the coil, the positive side of the coil goes to the distributor. It will work either way, but performance will be reduced if you do it bass-ackwards. I could try to explain this to a greater extent, but I'm sure our definitions of "straightforward" are incompatible.
 
You will be OK hooking both the coil and condenser to the male terminal on the distributor. 12 volt positive, huh? The wire from the ignition will be negative and go to the negative post on the coil, while the wire from the positive post goes to the distributor. (The condenser runs in parallel with the points, as it serves an electronic "shock absorber" for the points.)
 
Yep, I follow Tubman. So is there a wire that goes from negative side ofcoil to the distributor male terminal? Condenser plugs into same place?
 
Another problem. Without the rotior, the cap fits great. With the rotor on, cap doesn’t seem to sit right. 2 caps, 2 rotors. Just won’t seat as it should. Done till tomorrow.
