The heater switch in my 83 diesel is on its last legs. I'd like to have
a switch from as late a model as will fit it for the life left in the
later models. I'm assuming they're the same for all years. If not, I
change my request to a good-working dash-mounted heater switch that
will fit an 83.

New would be preferable, but I haven't seen them listed anywhere.

Thanks,

Jim
