My water pump pulley is 6&7/8" or 172mm diameter, and 2&7/8 or 74mm. If my water pump pulley is larger in diameter than yours, then my crank pulley should be smaller diameter making it able to fit diameter wise.

The diameter of my cut down V groove crankshaft pulley is 6.50 inches or 165mm. The depth from where it mates at the balancer on the engine to the center of the V groove is 2.0 inches or 51mm.

If the V groove ends up in the right place, along with the right diameter then a double row crank pulley with PN # 3614378 should work. You can just cut off the outer pulley groove for the power steering, or leave it in place in case you decide to add power steering later.

Anders i gotta laugh though. None of my old skool rulers or machinest scales as i call them have metric on them. I went and bought a small inexpensive 6 inch machinest scale with metric on one side today to measure the pulleys figuring metric would be easier for you to read. Its all good. I just thought i actually had one, but didnt. Now i got one LOL.
