I assume they are to hold drives in the bays?

If so then I’m sure you could 3D print some pretty cheaply and easily.

Ah, AT-Rails. You could 3-D print them. Or do what I do...if you're handy with metal stuff. I did this on an old Compaq Deskpro 386 and my GEM 386 that had the same style of drive rails....you need the right tools for it though. Tap and Die, Stepped Drill Bit, Dremel, and a Hacksaw, and a C Clamp or Vice (not to mention a solid place to work).

I usually buy a long piece of aluminum stock from a hardware store and make multiple rails from it. I try to get it as close to the thickness and width of the rails possible so I don't need to do any modification.

Cut the segments to length of the rail being reproduced, then mill it to shape using the Dreamel - most AT rails like that have a notch at the front for rthe lock-down plate. Just trace around it to get those parts hashed out. I usually also sand with 800grit around the edges to keep them from being sharp.

Next thing I do is I use a magic marker and hold the old rail over it and try to mark where the holes are in the rail, then mill those out, or only the holes needed for the device to be attached by attaching it to a device and running a line through that section. Then I center punch where the drill holes go, and drill through. THen I use a countersink bit to countersink the holes so the screws are flush, and then you have a drive rail.

In the case of rails like the Compaq Deskpro machines, you also need to drill two holes and tap/die those into place. That's pretty easy, once the rails are mounted to the drive, you can just slide it in, mark where the holes for screwing the rails on are, and then drill those, and then tap them for the apropriate computer screws - and be done with it.

An easier way might be with Wood and Wood Screws. harder woods like Maple moulding blanks work well. I've also used plastic for this. And of course 3D printing as said before is a valid option as well. Could probably find some already pre-rendered on Thingyverse and have them printed and shipped.

thats what i was thinking buy a alumunium tube ,wil try to do that thanks for the tips

3D print is easy for plastic rails, but for the pictured metallic ones it will be difficult.
Definitely had something like this in my sticky hands before , but not sure if its integrated somewhere now or just gathering dust in a box.
I will check my spares if there might be a matching pair an pm you.
Where are you located?
It may make a big difference for shipping from Germany.

If you're at the "I just wanna hold my %#$@ drives in!" stage rather than exact restoration stage, you can sometimes get double stacked popsicle sticks with countersunk screws to work.

I have similar situation with my case that I was searching for years and finally found. Needs rails made. It is slide in and click in by flat metal springs type latches. Stamped metal, U channel with two pins on one side to key into drive and hold them together then slide in. Springs on the sides keep everything tight without rattling. Luckily case has sets of two types so all I need is to measure and make them.

Cheers,

Those would be super easy to make with some aluminum bar stock for the rails themselves and then cut out a channel to use L-brackets for the bracket part.

i used 3m bolds with a bigger head all is oke now waiting for cf ide adapter 😀
everything is dishwasher clean

some more picks ,its the motherboard from hell wil keep the sx cpu because the 66mhz when i install it it becomes very hot even with a fan
i think its a jumper problem ,but for now iam happy with 33/40mhz
