I need a new water pump for my 69 Ram air 3 judge and I'm seeing a few different hub heights available. I don't have the original pump. Which is correct? Who makes a good quality replacement pump? Thanks

Early production 69's had a 4" hub height and mid year they changed to 4.5", what is the date stamp on the block?

Make sure you source the proper pump that matches the pulleys in your car. When Pontiac switched pumps as mentioned above they also switched pulleys to match the new shaft length. Or if you switch to the opposite pump you can match the pulleys to that... Until recently you could not get the 4" pump, you would have to find and old one and have it rebuilt. I know as I tried for over two years but recently Ames Performance started to carry them.

The crank pulley is a, 481037 YA. And the water pump pulley is a,. 9788886-XT. I'm guessing both are incorrect for my application. 69 RA 3 judge with power steering,. No AC. What would the correct numbers be for this application? Thanks
