Dash Lights for 1987 R-10

[Redfish]

I am going to order some parts I need to complete my dash from LMC for my 1987 R-10,,, I am not sure about one of the parts,,, wanted to see if anyone could help me out with this,,,

My dash lights only sort of work,,, and what is working is dim,,, I haven't tore it apart to see,,, kinda of want all the parts on hand before I start tearing it apart,,, my R-10 is my daily,, My dash lights only sort of work,, I am thinking that there will be more than one bulb needed,,, I don't know this though,,, So here is the problem,,,

In the LMC catalog,,, They show for the 1973 to 1980 truck,,, part number 36-0224 instrument panel bulb,,, number needed- AS ( as required ) makes me think you need more than one.

But I have a 1987 R-10,, you have to go to the next page in the catalog to get to the parts I need for my truck ,,, they show no bulbs Will,,, the bulbs for the 73 to 80 C-10 fit my truck,,, how many do I need if they do ?

I also need a new horn,,, mine is original ,,, nothing wrong with that,,, but its weak,,, could just be from age,,, any suggestions as to what I could do with that?
