The H front weight is part # 6788D (single weight).
But if you want a set then it's part # 48600D (which consists of two part # 6788D).
Want to put a second set of weights on? Then you need part # 48602D (which you guessed it consists of two part # 6788D).
Of course, then I HAD to look at the rear weights.
Part # 6818D (single weight)
First set part # 49329D (consists of two part # 6818D)
Second set part # 49330D (consists of two part # 6818D)
Third set part # 49331D (consists of two part # 6818D)
So if your wheel weights are subject to a Farmall Police inspection just remember that they are two, four, or six individual weights and were not installed as a set! Otherwise you have the wrong part number on your weights.

I'm sure there has to be a reason for this but it seems to me just having ONE part number for each weight and a quantity would be so much simpler.
Couldn't you imagine the kid at the chain auto parts store looking up a part number like this in the computer nowdays. "Nope, computer says I don't have any of those #48600D weights. To bad those #6788D ones won't work. I keep tripping over a stack of them back in the corner. Computer says that's the wrong part number though!
