Correct distributor/distributor cap for FB engines

I just finished reading up on the fireing order. Its truely one complete cylinder bank and then the other side.. Its 1L 3L 4L 2L... Then its 2R 1R 3R 4R.

My 1937 Cord FB engine has an Autolite IGHP400611Q distributor in it with a cap that is a IGH63. Its a very old cap and I believe it to be an original cap. All the plug wire connections are marked with a letter and cylinder number... Like L3, R1, L4 etc. I know this is getting confusing as to whats correct. Hopefully others will chime in with more information. I will be watching this post...

Many thanks for your replies gents. I might have to look into getting a new distributor before anything else!

I have a new never used cap, cover and knob for the top. The cap part number is IGH-29. The cover number is IGH 30. These are the brown caps and covers just like what you are bidding on. The cap wire location numbers are from about 1 oclock position and ending up at the 11 oclock position are.. 7 4 1 6 2 5 8 3...

The numbers I have from an old newsletter are:
not supercharged
distributor IGP-4006
cap IGH-1063

I've got an Autolite distributor (IGP4002) that came with my Cord. Is this the correct distributor for FB engines?

Aside from having the distributor, I'm missing a distributor cap, but have found one on eBay. The link is below.

Is this the right cap for the distributor?

Many thanks in advance.
