What's the difference in ignition modules?
I'm on LMC truck looking at ignition modules, and they have different modules for different years. They have a 1974, 1975, 1976-77, and 1978-79 module. What's the difference between each one and does one have an advantage over the others?
My truck is a 75, the motor is a 460 out of an 88. I'm completely redoing all the wiring and ignition, so any wiring issues that would keep me from using a certain year wouldn't be a problem.

According to "the man":
Ignition modules, 74 (black grommet) and 75 (green grommet) are year specific and will not interchange. 76 to 79 (blue grommet) are interchangeable.
Ignition modules: 1974 is 1974 ONLY / 1975 is 1975 ONLY.
Blue module introduced in 1976 was used well into the 1990's.
D4AZ-12A199-C 1974 only
DuraSpark ignition modules identified by a colored plastic insert located above where the wires feed out.
2 others: One has a*red*plastic insert, the other has a*yellow*or*brown*plastic insert.
Red*module is*D7AZ-12A199-A*used in some CA vehicles ONLY.
D9AZ-12A199-C*(replaced D8AZ-12A199-A). One of these modules is*yellow , one is*brown*.. Since the part number was replaced, I cannot recall which module was which color.
These modules were used in 1978/79 302 & 351M/W vehicles sold in high altitudes only. 351W: Passenger Cars & Econolines only.

I'm curious if aftermarket modules use the same color grommets to identify them. I go to lots of parts swaps & find new ones in the box, but never knew how to ID them, as they all have their own part # on them. If the aftermarket has the colored grommets, I'll pick a few up as spares. Often they are really cheap, & are made in the USA, not communist China.
