Is this a direct replacement for double grove alignment wise with single grove water pump

Willys Jeep Parts Tech.:
You typically wouldn't have that set up. They follow suit. Email mike@kaiserwillys.com to help.

Does this pulley have the timing notch?

Willys Jeep Parts Tech:
No you would have to indent your own on it.

Why do I need to call? I have a 1948 Willys and I need this New Single Groove Crankshaft Pulley - what do I need to know? Bill
