We received your order for the parts 839330 and 839331. Both parts are expired, but I do have a source for them.
Attached is a quote showing the new prices for these expired parts. The price does increase (my source knows how rare these are).
I also included a good used one of the housing that we have out back.
Please review and let me know what you would like to do.
I am sorry I can't find these at a more reasonable price, but they have been discontinued for 18 years!
