Spark plug gap for a 1974 swinger

[1974dodge]

Hey guys and gals, I'm looking for the spark plug gap on my 1974 dodge dart swinger. It's a 225 /6 and I'm doing a tune up but I can't find the spark plug gap I looked in my Haynes repair book but I couldn't find the gap anybody know?

Factory ignition I always went .035. FSM I believe recommended .033 to .037 so I just went in the middle.

.035 on dead stock, .037 if your running a blaster II coil. i havn't played with my gap on my slant with an MSD yet
