fit well in the location the old one was in. But it seems to have some issues with Bleeding out the air. as I have to pump it up after it sits for a while other wise it works fine. I bleed the system out until there was no more air seen coming out of the lines and all the fluid was replaced with new fluid too.

Excellent detail and workmanship. It took only about 20 minutes from start to finish to remove the old master cylinder and replace it with this product which was an exact fit. The chrome on mine was very well done and I like chrome.
