The speedo is cable driven. I think it'sa 92 only because the guy from ebay said so. It might not be. The oil pressure gauge doesn't work because the cicuit board on the back is broken. So how do I find out what sending unit I need If I don't know the year for sure. Oh and yes its a 4.0. How to you swap the sending unit. Does it require splicing more stinkin wires together? Last question, any special place I should get them?
