Source for door latch springs ? ?

[jason@snakeriver]

These have been common for the past 50 years in all the trucks. But I need to find a source for the coil door latch springs. There apparently are left and right hand sides.
I keep robbing old parts trucks, but I am running out of doors.

I replaced my right door one with one from a left door. no proplem. It works GREAT! FTG2 Wiggles USS EDSON DD 946 1969-1973

An easy fix ! I opened up an M35 door and low and behold it had been repaired.
Open up the pinch fitting that holds the spring and throw away the bad spring. Next mash the pinch fitting back down into the plate.
Cut a 3.5" piece of 1/4" rod and weld it to the top of the latch plate. Install a 2.5" compression spring that slides over the 1/4" rod. Compress it on and weld a 5/16" nut on the end of the plate for the spring to work against.
Very easy fix.

Jason a couple of years ago somebody on the "other m37 forum" made up a bunch for that truck. I would think there the same. I bought six at the time thinking someday I might need them. If you ask over there maybe somebody's (really anybody) memory is better than mine, could tell you who and where they were made up.

Anybody know of a source for just the spring? I can't see paying the prices some of the places are quoting me for the whole latch when all I need is the spring. Prices vary from 40 up to 85 for the whole latch.

Got a pic or specs, particularly collapsed length and spring rate? There is a very good chance you can find something that will fit on McMaster with a bit of searching. Might not look original though.

Anyone have a PN or NSN? I can run thru the procurement history of it.

Don't have pics or specs, I looked at McMaster and did not see anything close (would not be surprised if I missed something)

Only part number I could find was for the whole latch.

I'd previously discussed magazine springs for Grease guns with a spring manufacturer. If you can provide them something to go by, I'm sure they can make it. Sent up cost is the killer. Probably looking at $400-500 for each run (left and right). After that I would think the springs would be $1-2 each. I would be willing to look into it further. However, I wouldn't want to get stuck with $1000+ of springs for years to come.
