I have an extra Horton set up but it is for the 94 thru 98. 5's. If they will fit on the 98. 5 and up PM for the price.
As far as installing them, they are not to hard. You have to remove your old fan and install the clutch fan, remove the fuel filter and place the temp sensor in the block. Put the pressure switch in the air conditionor head line and install the harness. Then run the switch lines into the cab to your designated place and you are done. Not to hard.
