The elbows are "Cannon" brand military spec connectors w/ 90 deg shell. There are two different sizes, PN's 3108B20 AND 3108B32. Some come with a green coating while others have a silver coating. It's also an option to buy all green and sand blast or chemically strip off the coating to reveal the raw silver color underneath.


In total you'll need:

(Size 32's)
2 silver/unplated for bailout bottle box
1 green plated for Flux Capacitor

(Size 20's)
3 green for DS pontoon
1 silver/unplated for VSR
1 silver/unplated for Flux Capacitor

Chances are you'll find lots of parts under those PN's but they'll be Amphenol brand connectors and not Cannon. They're all made to the same mill spec under the same PN but only the Cannon brand connectors are correct. The only exception to this is the C-car flux capacitor which uses a size 32 amphenol connector on the side instead of the Cannon style.

A few more notes about the PN's... What I have listed above are the base part numbers, but when searching you'll need the -tabulation at the end which specifies numbers of pins, and if it's a plug or a socket. Since the connectors don't actually connect into anything meaningful on the car plug/socket style and pins do not matter.

So for example the PN you'd want to search for might look like 3108B20-16S. The PN breaks down as:

3108B (Connector series, 90 deg right angle plug)
20 (AN size)
16 (number of pins)
S (Socket)

You'll also need the plastic dust caps that would normally protect the pins/sockets. To mount the parts to the car typically production used a screw to mount the dust cap, and simply inserted the plug into the dust cap. There wasn't much else holding the parts in place besides the friction between the plug and dust cap, so they tended to fall off and go missing pretty easily. For replica cars you can secure them better by disassembling the connector, drilling through the internal socket to mount with a nut and bolt, and then reassembling the connector around the socket. Essentially you're adding a stud to the connector that you can secure with a nut to whatever it's getting attached to.

Each plug is made up of about a dozen smaller pieces. In some cases you may only be able to find a seller with the correct shell and you'll have to source the strain relief at the top part of the connector and the dust cap separately. Here's an exploded view of a size 20 connector for reference:



The connectors can be crazy expensive, and the few sources that were found back in the day with lots of parts in stock were quickly depleted. Your best source for searching now are websites that allow NSN searches for military/aerospace parts. Every great once in a while real ones will pop up on ebay. Or you can find someone who's selling castings.

If you have any other questions or need clarification on anything let me know.
