Hi,

I'm finally getting around to fixing my over heating problem (1940 Chevy with mid 50's 235) and when I get the pump off I see that the adapter plate is not compatible. The pump has a round turbine that fits into a round hole in the engine block, the adapter plate has no such hole.

The pump installation instructions say that I must use a '41-'52 Harmonic balancer and pump or a '53-'54. Can anyone tell me from these pictures what I do have? (must be a pre 41 or a post 54???)

What does a proper 41-54 water pump look like?

There was also mention of an adapter plate between the pump and the block, which I did not encounter....?

thanks for any assistance,

Doug
