The first apex seal on top came out of my "rest of the world" fb bodied, no emissions, no solenoids, no air pump, sa22c vin, rear seats, rotor shaped wheels, rear discs but no LSD .... first gen .... 81.

Yes, I came that way from factory, and the owners manual itīs in spanish

The second apex, came out of a friends 80

and the third, its a normal, brand new, mazda made 12a apex seal

Ive never seen before an apex like the one in my car on a first gen

If anyone has some info please share

they are ferrous (checked with a magnet)

quick note: it only had one spring.

looking at its desing, you might think it came with two, but no.... just one
