Where can I find a Power Steering Pulley for the pump,  for a 1970 Cuda small block?

there are 3 types of pumps so which do you have
Saginaw , Federal & TRW all use different pullies  :alan2cents:

I have a Saginaw.

I think it should look like this picture.
I think they were different between A/C  and non-A/C. Mine is an A/C car.

First have you talked to @MoparDave @ Roseville ?
In theory this should be the easiest pulley to find as GM used the same pumps & may use the same pulley

CudaHead

Thanks, I will.
I did notice that in my search, many of them showed as GM and looked the same.

my first question since you know you have a Saginaw pump now. would be,
1.what is not lining up ? it would be helpful if you posted a picture of what your seeing.
2.do you have the correct brackets. Nothing between an AC vs NON AC car in relation to the pulleys and brackets are the same. it has to be A = A and B = B. except the only pulley that is the same is the power steering pump pulley.
3. is the pump that you have, have a pressed on pulley or keyed with a Nut?

I need to clarify.
I am working on a new project. A 1970 Grande Coupe Convertible.  It has a 318 Automatic with A.C but no Power Steering. I never understand why someone would order the A/C option but not get Power Steering.
I called http://bergmanautocraft.com/ to get a complete PS system.  He sent me the Saginaw pump with the brackets and pulley.
The bracket did now work at all, so we had him send the correct brackets that look just like the one's on my 70 Cuda that has a 340 with A/C. They came in and look correct now, but the pulley was a three spoke and stuck way out beyond the 3 grove pulley on the crank.
The picture above is from my 340 cuda. I tried to pull the number off it and got "58 99673" I have old eyes, so I may of missed the numbers. I could not find that number online.
I found some numbers out there and the only one I think may be corrrect is 2951989.
I consulted the parts manual and of the numbers there, 2951989 is the only one that matched.
bergmanautocraft is sending me another pulley, but I'm tring to get ahead of the game in case it does not match.
Working on a project is so much FUN.

"is the pump that you have, have a pressed on pulley or keyed with a Nut?"    Yes  "keyed with a Nut"


MoparDave

well.  :huh: you may just need a 4 groove crank pulley. Does your other AC car have a 3 or 4 groove pulley on the crank? I don't see how you can get anything to align with that crank pulley.

The 340 Cuda is a three groove pulley. I've never seen a 4 groove.

Good chatting with you this AM. here are a few things that you want to look at.
1. the neck of that tear drop pump. from the mounting face end of casting for the shaft.
2. the length or height of the crank pulley, meaning from the damper to the very face.
3. the diameter of the crank pulley also. compared to in the picture, the one on the blue block is incorrect.

pulleys are always a big issue when you don't have the correct piece.

as you can see I have 3 different crank pulleys.
