I pretty much agree with the above. If #1 is on TDC, compression stroke, then when you drop the distributor in you can rotate the distributor body CCW so the reluctor is lined up with the pick-up(std Chrysler electronic) or points contacting but "about to be separated". That will be close to #1 firing position which will give you your #1 terminal. When all is said and done, it should look like the Motor Manual SB distributor diagram. While you don't absolutely have to have their #1 as your #1, pre-made spark plug wires are made to fit that arrangement, and you won't have some wires which are too short or way too long.
