Source for TNC connector pins?

I have run into stuff like this before. Typically is is cheaper to just buy a new $23 TNC connector from SteinAir.

Or...

This stuff's not rocket surgery...

No pins there either but looks like much cheaper kits that can be tossed, assuming the they have the correct pin.
EDIT: They're not the correct pins, at least the ones that are depicted aren't. The search continues...

There's no rule that says you have to use the rest of the connector that you got in the kit. Find one that fits your cable, and install it. Throw away the one you lost the parts for.
Ebay isn't the only option, but $20 (or $200) for a $2 connector aren't the only options, either.

The above P/N is for RG58 cable. The DigiKey P/N for a similar connector that fits RG400 & RG142 (more common in GPS installations) is ARF1135-ND and list for $6.67 each. This is for a whole connector assembly, not just the center pin.

No, I think the TNC specifically mentioned in its datasheet for RG400 is this one at about $13 (ARF1683-ND) -

This appears to be the cheapest all-crimp RG400 TNC connector from DigiKey -

Unlike some others, this has a snap-in action for the pin into the body - shown best in this video -

I just used two for my GTX335 hook-up.

RV6_flyer's post has the pin in question, which is really meant for RG-142 but will work for RG-400.
Mouser used to sell them by 1 count but when I ordered, they were out and required a minimum 750. The quality of the connect is very good.

The whole point was to NOT throw away $25 worth of perfectly good parts when a $2 replacement pin is available, albeit in large quantity orders only, it seems.

Or a $2 complete connector, in quantity one.

Look at the specs, a Mil connector would be beryllium copper center with gold plating and a brass, silver plated body. The materials and corrosion protection are the big differences. I have a bunch of military BNC connectors that are 60 yrs old and the silver is still good. Nickel on brass not as durable. Just so you know. No recommendations made.

Maybe, but it also depends on the source. The $27 TNC connectors from Spruce are not AMP, but TE Connectivity (Tyco) part number 225555-6 and are listed as "Mil--Type Plug Connectors" and interestingly are not spec'd by the manufacturer for RG400.

I can't seem to find the materials they are made from, but the rubber seals do seem to indiicated they are waterproof, which is not usually a requirement for us.
