The reason I ask is that probably, like many,my J325 has been retrofitted ...twice. The other day I noticed that on the control cab there are a couple holes where there may have been a switch; my machine has two cabs; one on the RH side and one in the back. The holes are toward the back on the control cab.
I'm curious about what was originally there. I've looked for pictures watched a bunch of videos but that area doesn't get much attention.
