these agp slot retention brackets were seemingly included with some motherboards back in the day as an optional accessory that the user has to install them selfs. seems like few if any ever got installed its rare to ever see a motherboard with one installed.

i found one site that use to sell them back in the day for $3. but they no longer have any in stock.

they seem like a good idea since they have a tab to lock in the back end of the gpu just like modern pci-e slots do.

is there any place u can get these now a days or does someone like 3d print them.
