I need this for a 1962 Cadillac :
never seen that before. both of mine hook on a hole on the power steering pump bracket. forward of the carb.
Doesn't look good enough to be a factory made bracket.
Bruce. >:D

I don't know... It is a '63. I have included the picture for illustrational purposes.

This problem is haunting me from day one. The car always had a makeshift throttle return spring. Now I have an expensive reproduction which is shorter. Do you know if yours is correct? Do you have a picture?
Is it 63 engine? I don’t know 63 engines
No, it is a matching numbers '62 engine in a '62 Cadillac. I have included the picture strictly for illustrational purposes because I was not sure if I use the appropriate terms for the issue.
Attaching it to the power steering pump bracket works as you have said. So I need no bracket because there was no bracket.
Thank you all!

Every picture on Google has it on the Power Steering Pump Bracket......

Just a matter of finding the right spring.
Many have been modified when they change carbs, manifolds, etc. Best to go to a motor cut away or illustration when looking for these levels of detail like in the specifications - GM Heritage archives - download for free. Or shop manual or parts list. Absence of a part is also valuable to know. If it ain't in there, it don't belong.
Here is where mine was factory.
BTW...That's a '62 Engine in a '59 car.
G'day John,
I can't see that arrangement as being factory simply because the spring is not at 90 degrees to the throttle shaft.
Any offset of the spring will result is a sideways pull on the shaft, so every time the thottle is opened, the spring will be pulling the shaft sideways, and over time, will wear out the pulled side within the carby.

I gotta agree with you. But that's where it was when I bought it, so I ASSumed it was correct. So...that is where I put it when when the engine was put back in.
Looking at 6262's pictures, his P/S pump sits up high on the engine, whereas mine was down lower mounted to the block and exhaust manifold.
My '60 CDV had a 454 and TH400 when I purchased it, and the replacement engine I purchased was from a '61, and that had the pump sitting up high.
I mounted the return springs towards the rear as it had the Holley 650 spread bore carby from the 454, and I had to fabricate the kickdown bracketry to attach to the throttle lever, to run the factory '60 Transmission kickdown lever.
Bruce. >:D
The reasoning I got was that the original purchaser liked to do his own service work and hated the oil filter canister. So, he purchased a newer engine and added all of the 59 accessories to the newer engine. ::)
Who, is 1959 that could afford a Cadillac did their own service? I thought Cadillac ownership then, showed you were a 'made man'.

Jim, can you point to an illustration which solves the problem? I have the shop manual and the MPL but have not seen a picture which answers my question.
I think I have the right spring because I have bought this item:

This is the reason why my friend who owns the
'63 in the first picture has this bracket. He holds the same opinion as you.

I think I have found a proof that the throttle return spring indeed attaches to the power steering pump. The second and third picture show how my actual car looks now. However I recognize in this moment that my spring has now the opposite direction than Caddyholic's and Big Fins'. ???
