Derek,

I am not sure if the same coil was used from the 122s, thru the 140/160 series, the 240 and also the 700/900 series. Maybe someone can help shed some light on this.

I noticed that my 144 (Euro) and my 1996 940 (Euro) have the same black coils, and the 1975 244 (USA) that I pulled the electronic ignition from for my 144 also had the same looking coil.

The coil in the 144 was replaced with the blue coil in 1988 and it still runs fine. The original coil is in the garage somewhere, probably will work just fine if I plugged it back into the car.

Interestingly, my 144 and 940 share the same exhaust gasket where the four pipes from the manifold merges to become two...perhaps same gasket on the 122 as well?
