JB racing twin plug distributor help with rotor direction

[Blander389]

Hi. Doing my first valve adjustment on 78 case 3.2 short stroke, twin plug. Got the crank lined up to Z1, now looking at my JB distributor with top off. The cylinder/plug placement is easy as each plug is labeled on the cap (ie 1T, 1B, etc). Plus the dizzy housing on the side shows a Z1 Top marking which is right next to the 1T plug when the cap is on. What I just want to double check/help with is which side of the rotor “arm/hands” (lack of better words) should be pointing to that Z1 Top/1T plug location to signify I am at TDC for cylinder #1. There is a top arm and a lower arm. Cpl pics attached. Is is the lower plastic side that has the arrow engraved and red CW in marker that should point to z1/1T for TDC cylinder #1 or is it the opposite higher side??? I’m thinking it should be opposite of the picture i posted as the CW on the dizzy case is the index point for bottom plug 1B and lower plastic rotor arm is marked with a CW red marker...so maybe those should line up? Appreciate any help on direction here. much thanks!

Check the rockers are loose on #1 to make sure it’s on power stroke. Then make sure the rotor is pointing to #1 .. top and bottom. Follow the tracks for #1 inside the cap .. from the nipple inside to each terminal outside. Use a multi meter to confirm connectivity if you’re not sure which nipple is connected to which terminal.

I sent Jim a message about your question yesterday, did he respond to you?

Hey. I appreciate it. I was able to get them on the phone. Should’ve thought of that first. Jim explained to me he marks the red CW on the rotor to line up with the CW at 12:30 position on the rotor. So basically I had it backwards in the photo.
