A/F/R gauge for tuning

1MeanA said
I use an old Innovate LM1 to tune my carb. I think I paid $250 many years ago so not cheap. I weld an O2 bung into the pipe near the header and run the cable out through the passenger window :). Its a temporary install.

Have a 02 bung already from earlier. Don't want a permanent one in car just for test and tune then throw it in the drawer till next time.

Is the cable long enough to run from under the car through window?
