I got the point but according to you she doesn't have access to the resources necessary to search for odd ball parts. I live in a rural area where logging and fishing are king and local parts stores routinely have to find shit no ones heard of since Christ was a kid. Ask your wife for a fuel injector for a 1942 Hercules DOOC diesel engine ( auxiliary hydraulic system on a 1938 52' salmon boat) From what you said the look you'll get is a deer in the headlights look . I didn't get new ones but they were able to send mine off and had them rebuilt i had um back in 10 days
