Miata Rear Main Seal Installer Tool Fits 90-05 Miata Engines

Rear main seals suck to install, especially if you're trying to install them while the engine is still in the car. You can push the seal in too far, not enough, or just crooked. 

I've had to start over more times than I care to admit, by tapping seals in with sockets and extensions, or even using someone else's 3D printed tool, which is why I made my own. They may be small adjustments, but now I know the seal won't get pushed in too far and the tool won't get stuck afterwards.
