Air/Fuel Gauge on '68

I was thinking about getting a A/F Gauge for my 68 mustang to keep a check on how im running....is this a good idea?

how do you hook them up?

You'll have to have a bung welded into the exhaust for the o2 sensor. Then it's plug and play from that point. Kinda a waste of money on a carbed car IMO.

yeah ive just read some people suggest it

If its a narrowband A/F guage dont bother. They just make cool lights. They are worthless, since you cant actually tune off of it.

If you purchase a wideband A/F guage then yes it is worth it. If its NA, supercharged or nitrous fed, then you want it as close to the collecter as possible. If its turbo, you want it 8-10 inches frrom the turbo.
