I have one of these (part of an L plate) on a D750. It looks like a universal-fit plate, but it is not. Instead, it has a stud that threads into the plate with a pin that fits into a round hole on the bottom of the D750. There are two positions for the stud, corresponding with the two places you can put the mounting bolt (1/4-20). If you are using the adjustable L-portion, in order to mount it so the plate is flush with the left side of the camera, you need to move the stud to the leftmost hole for it and use the corresponding mounting bolt hole. Here's the problem: if you mount a strap loop, it will interfere with the battery door. The solution is to put the (heavy sheet metal) PMG strap loop into a vise and bend it with a hammer. Use a block of wood to transfer force or you'll mar it Ditto copper jaw plates. This works, and makes for IMO a perfect D750 L-plate, but I don't think any other accessory will ft there unless you shift the pin and bolt to the other position - and then the L-portion is not flush with the camera. With the L-portion, it's the best L-plate I've ever used on a Nikon Dnnn.
