Questions: What are the width/length dimensions on this belt? My 52 M38 has double pulleys on my water pump and shaft pulleys but am going to put a double pulley onto my 12V alternator when I swap.

.4 of an inch like original.

Questions: I have an alternator on my cj3a and want to know if I should use just one belt or do I need to use two seperate belts. One from the double pulley crank to the water pump and one from the double pulley crank to the alternator. Is this correct or should I just use one larger belt for the crank, waterpump, and alternator?"

You should be fine just using the one belt only.
