Hello

It seems the that Cardone 58-107 Water Pump (pic attached) with the longer hub length (Approx 4.35") is very hard to find.

Is there an alternative/another manufacturer for the 58-107?

You can find the shorter 58-107 pumps all day long. Unfortunately, this pump does not work with the pulley I have.

What are the options for this? Is there a pulley that makes up the .70" difference? Of there is, can you supply me the part number please?

This is odd because the 58-107 is for the NON factory A/C cars which I thought would be more prevalent than the A/C car that use the 58-108

Thanks , in advance

NAPA WP58107 (that number is surprising, isn't it... ), for $36.79. NAPAonline says it's available for order.

LOL.. checked them all but NAPA..

Thanks Joe

Ok.. so did some more checking with ALL the autoparts stores and even called A1 Cardone direct and spoke with them..

This pump is OBSOLETE and will no longer be produced.

So, I am guessing the only option is to use the shorter pump and find a pulley that will work?

Since there is a .70" difference and the stock pulley is about 2.3" from hub to center of the groove. One would need a 1.6" hub to center pulley with the 5/8" pilot hole.

Anybody know where to get one of those?

The original GM part number is 1389457. If you Google that, you will find some N.O.S. pumps, but be sitting down when you look at the price. Have you considered rebuilding your original?

In any case, here is 1389457:



Here is the A/C pump. The only difference appears to be the shaft length.



This is the pump for a 1964 Buick 300, available at RockAuto and other parts stores. I don't have the hub height measurement, but that shaft appears to be long enough to allow the hub to be pressed closer to the tip if need be.



The 215 pumps both appear to use the same straight-blade impeller. The 300 pump uses a curved-blade impeller. Additional photos are available here.

No luck finding the pump except at the Buick farm for a very high price.

I think I will just machine up a .70" hub spacer. I think this will be the easiest, since finding the right pulley is also proving to be a bit difficult.

Seems very odd that they would make the NON A/C pump obsolete and continue with the A/C pump?

Thanks for the help.

If you look the 300 has an extra mounting hole that the 215 does not have.

I sent my original 215 water pump to Rock auto to be rebuilt. Came back in about 2/3 weeks. Was not a problem.
Good luck

Never looked very closely but the 3.8 buick V6 has the same front cover. I am sure you would know how close the water pump is. Look forward to your reply.
