Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.

Frequently Asked Questions
Is this an OEM Cometic gasket or a reproduction?
This is a genuine Cometic-manufactured OEM replacement gasket built to factory specifications.
Will this fit my Twin Cam transmission?
No — this gasket is specific to Milwaukee-Eight transmissions. Twin Cam motorcycles require a different part number.
What's the thickness, and why does it matter?
0.032" thickness. Gasket thickness affects sealing performance and bolt-down pressure — use the correct thickness for your engine.
Do I need any special tools to install this?
Standard gasket removal and installation tools work fine. Clean the gasket surface thoroughly before applying the new seal.

These seals are the only ones I'll use. others came close but, for me, these are best.
