Are there any real differences in the headlight switches between a '77 Dodge Van/Motorhome and a 70's A body other than the handle you pull out. I am doing some work on my neighbors motorhome and the dashlights don't work too good as you try to adjust them. They only work at the dimmest setting or intermittently as you turn them up. Actually you have to wiggle the handle to get them to flicker. I have a few spare A body ones and was wondering if I could use one in the motorhome and just use the pull handle that is currently in it with the A body switch.
