Here's a picture of the tone arm without the needle cartridge in it. One side has the contact plate that also contains a metal stud that slides into a recessed area on the side of the needle cartridge, the other side inside the tone arm has a metal clip which exerts pressure on the needle cartridge to keep it snug against the contact plate. To remove the cartridge, I simply push the cartridge towards the metal clip side and just pull it down. To reinsert, I just push the cartridge back up into it and it snaps into place.
There are 3 wires that go into the contact plate, you can see them in the photo. Two are for the two different contacts for the 2 different needles, the third wire is a ground for the cartridge. The oval hole you see in the top of the tone arm is for the lever to at the top of the cartridge so that you can tilt the cartridge to the 78 side or the 45/33 side. I did look up the needle you mentioned above, I'm sure I can figure out a way to mount it in there and but would have to somehow solder and/or connect the leads from the new needle, because the old contact plate will work for the new needle. The little Philips head screw you see with the little metal plate (there's another one of these on the other side, not visible in the photo) are used to keep the contact plate and the spring plate from moving and/or falling out. I might be able to use those for somehow anchor the new needle?
