Can I order Mossberg 500 parts for an old New Haven?

[AHelm3]

So a friend of a family was having some issues with a New Haven .410 pump made by Mossberg.

When I got it, the gun wasn't pulling rounds out of the mag tube consistently. Even if it did, the round would not feed into the chamber.

I've managed to get it to pull rounds from the mag tube, however I believe there is an issue with the elevator assembly which is causing the issue when chambering. I was going to just order an entire new one, but cant find any specifically for this model. Will one from a Mossberg fit?

I have two New Haven 12 gauges. They are identical to my 500 except for a minor difference in the pump arm and mag tube, but being as the part you are having trouble with is unrelated, you should be fine with ordering the part for the 500.

If it's a "600" then yes. IIRC there were other Mossberg-made "New Haven" guns that weren't rebadged 500's.
