Identifying engine, serial doesnt match pelicans? Options

[stateofidleness]

i found the serial number on my engine and im having trouble identifying it. i tried comparing it to the FAQ on Pelican:

"A very good indicator of what type of four-banger you have is the engine code. The engine code is located in front of the oil filler, between it and the fan shroud, on 2.0L cases. The code should start with "GA" (for 73-74) or "GC" (for 75-76). The European 2.0L engine code starts with "GB". The 1.7L and 1.8L engine codes are on a flat spot located toward the right-rear of the top of the case. You may have to push some hoses and wires out of the way, and clean off a lot of dirt to read them. 1.7L engine codes start with "W", "EA", or "EB" (for the 73 California car). The 1.8L codes start with "EC" for the US model, or "AN" for the European model."

now im pretty sure mine is: 6A012526

so far ive been under the impression that this is a '76

can anyone help clarify?

Timing hole plug, part number 021 119 233 A . Listed as NLA (rats!); used is probably your most cost-effective way to go.

Picture of the flaps and such:

It's an "exploded" picture, so it isn't the clearest... The flaps go under the engine tin at the very front, right up against the fan shroud. They point the air coming out of the fan to where it needs to go. The cross-shaft runs across the front of the motor, just behind the fan shroud and just in front of the oil filler tower.

You absolutely need the right-side flap! When in its "open" position, it separates part of the air flow and ducts it into the oil cooler. Without the flap there, air will bypass the cooler, or worse yet hot air from under the engine will get sucked up into the cooler! Oil temps will go up...

It's best if the whole flaps and thermostat are there and working correctly. Failing that, having the flaps in place in the "fully open" position is OK. An alternative to that is only having that right-side flap in place, and having it fastened down in the open position.

If someone has done that last, you may have to pull the right-side engine tin off to tell...

A lot of people have reasoned that "flaps block air, removing flaps means more air". That's why the flaps get left out, but the reasoning is very wrong. And leaving them out is a Very Bad Thing...
