I have 2 brand new in a box water pump spacer plates #9796349 for many years of Pontiac Blue Block (commonly known as a Pontiac Big Block !!!!)
Online going rate for one of these plates seems to be $20-$25 US plus shipping, about $28-$35 Canadian plus shipping.
I will sell a single or the pair, $20 Canadian plus shipping for the single, $35 Canadian plus shipping for the pair. $5 will go to Canadian Poncho if I sell both.
Feel free to contact me with your exact application if you are unsure if this number is correct for your engine.
