I wasn't saying they didn't exist, just saying Ive never seen them, and its probly because I haven't had to much head trouble.
That's OK. Lots I don't know about either.
I still don't know what an "Ap" is. I still use VHS videotapes, and play cassettes in my B2200 (but it is a CD-cassette stereo). I don't know what GPS and Garmin/Garvin do.
its all cool, I just have to learn what some stuff on this mazda motor is, like the box thingy on the front of the air filter housing.
