50 coupe

You may need to contact them. They are under new management in the past year so looks like they offer different conversion kits than in the past. I installed one of their conversion kits almost 10 years ago. Over time their kits and parts recommendations have changed based on what parts were affordable and commonly available at the time. So, what is on your car now may not be what they carry now.
 

OK, thanks for the info. Looks like the wiper knob has a 'divider' in the hole that slips into the gap between the prongs that turn the control cable. I haven't looked at the radio knobs so I will pull one and check it out. Chances are slim, I gather, that the radio will actually work when I put it back in the car but I will need the wipers to work. 
Funny thing, I could not figure out where the control for the wipers were until I pulled the instrument cluster and got up behind the dash. Saw the cable hanging down and noticed that odd hole in the top middle of the dash by the wind shield. Thought maybe a PO had a compass or Jesus statue there at one time. Popped the control end of the cable in there and voila, mystery solved!

OK, thanks for the info. I cleaned up my original junction block and will be using it. I see were it is useful for joining wires to different circuits also. This is my first wiring rodeo so learning as I go.

Thanks for the suggestions guys. Knowing that the bolt was grooved and press fit into the parking brake drum was a big help. I was able to pull the bolt into the grooves that hold it in place and with some vice grips work the nut off of it and drop the drive shaft. Then got a new nut, tightened it down to pull the bolt back into the grooves in the hole in the parking brake drum. Solved.
