Looking for source of RT-524 Radio Bracket

[cruzinz28]

I'm trying to source what I call an "enclosure bracket" that mounts around the RT-524 Radio and allows you to mount the KY-57 Encryption boxes on top. I'm not sure if they were installed in any particular vehicle but I have seen this setup installed in two M151's so far from what I can find on the internet.

If anyone knows of a source for this setup I would appreciate any information you can provide.

Officially these were referred to as "security covers" because they were originally intended to provide a mounting for the KY-38 and KY-57 crypto units. Unfortunately, because they were plain steel most of the ones that got out went to metal scrap unless someone knowledgeable say them and kept them out of the metal bin.

We installed them on every possible configuration of vehicle you can imagine in the 80's. So there were lots around, but like Papakb said, most went to the scrap heap.

Try Fair Radio. I have bought two from there in the past three years.

I just got a break in work to check everyone's posts. I really appreciate the help!

Yesterday I was able to find a part number off a diagram and that led me right to 123mack's suggestion. I should have one on the way after my order processes along with some other things I decided to buy while I was shopping.

The funny thing is I heard from two other people that they were surprised I found one and that they didn't end up scrapped too.

Where in the heck did you get this crazy idea??

 

[ZiggyO]

Can you post a component number? I actually am looking for one as well.......

Try private jarhead, he deals in military radios

Okay... my lead might have washed up. They "can't find" the one they had listed for sale, but are still looking at this time.

So, any other leads would be greatly appreciated! I did try to search for "Private jarhead" on here, but that user name doesn't come up.

As for part number(s), here you go:

NSN 5810-01-043-4643
SC-D-446186 (Left Mounting Plate)
SC-D-446187 (Right Mounting Plate)
SC-D-691342 (Large Mounting Plate)

At this point, I might consider borrowing one from someone as well if they could part with it. This way I could take measurements from all three components and make an accurate CAD File. I do have a friend at a fabrication business that could replicate it for me/us and probably even spray it the correct OD Green since they also produce smaller components for military projects regularly. Just a thought if I can't find a lead on one.

All though TB 11-2300-478-30-1 states the following:

"(1) Transition installation - All existing COMSEC Vinson security equipment will be transferred from the M151/M561 to the HMMWV except for the Support Assembly SC-D-691342, NSN 5810-01-043-4643."

This arrangement would work better for me when combining the radio installation with the VIC-1 Intercom System in my truck. CARNAC also confirmed that he did see them installed in this manner in the field as well. This way I can utilize the Intercom mounting plate as it should be, vertical, and them relocate the two speakers I have to alternate locations.

you have to go on the internet to find his website, he's not on steel soldiers

 

[cruzinz28]

Joel - Thanks for the tip. I was able to fins his website and reached out to him as well.

Well, took a little bit but I did locate one. Each person I was referred to forwarded me to another person. The last person had 1 NOS bracket left.



i am making a detailed CAD file of all three pieces. My plan is to give the file to my friend who works in a fab shop to see what the cost would be to reproduce these if there is a decent amount of interest in these.

And then share the CAD file, please, so we don't lose it to time when you're done making them!
