Sending Unit 
I've replaced on in my 87 once..
BTW post some pics of those 40s you got man.
and I say bob that bed and put 'er on!
Coming along Blake.
glad to see you decided to stay Toy axles for now.
I'm just waiting on my new rear axle to be takin' out so I can pick it up.. its aggravating as hell.
Iv only got one of my 40's right now. The tire shop still hasn't swapped em over for me.
i thought the sending unit was the part that told the gauge how much gas was in it...
Ill take a pic of the lone 40 and what the gas thing looks like.
