How unusual! I had a 1990 as well. 1990 was a transition year. My R10326 was (originally) a sd1 3.5 Flapper. I had the impression you had a 3.9 You are disolaying a Flapper 3.5 pump. Take a look at this page. https://www.gomog.com/allmorgan/pumps.htm

Sd1 pumps are easier to find. At least they used to be.

You might have to have the nose of the pump cut off. That did what Morgan did in most cases. Use your current pump as a template at a machine shop. That is what Melvyn likely did. Follow his lead..just don't pay his prices..5 times more than its worth! rofl

Remember, that the most important tool in any mechanics box is patience.
