I did this one other time a few years ago and used a master cylinder from a company in Knoxville, TN. One problem I had with it was that it was hard to get its cap off without first removing the cap on the brake master cylinder. The new cylinder from Moss appears that it won't have that issue. It's this one under 180-697: <a href="https://mossmotors.com/180-697-clutch-master-cylinder-replacement-3-4-bore" style="font-size: 12pt;" class="">https://mossmotors.com/180-697-clutch-master-cylinder-replacement-3-4-bore</a></div><div class=""><br data-mce-bogus="1" class=""></div><div class="">The problem is that there's no label on the cylinder stating whether or not it's DOT 3 compliant. The brake master I installed (<a href="https://mossmotors.com/180-767-brake-master-cylinder-aftermarket" style="font-size: 12pt;" class="">https://mossmotors.com/180-767-brake-master-cylinder-aftermarket) </a><span style="font-size: 12pt;" class="">is an aftermarket replacement from Moss, and it's labeled as DOT 3 compliant. I'm under the impression that most parts sold in the US are supposed to be that way, and have also been told that these new cylinders use a synthetic rubber that the old original cylinders didn't have, so the fluid is less mission critical and shouldn't cause the rubber parts to deteriorate.</span></div><div class=""><br data-mce-bogus="1" class=""></div><div class="">There's nothing on the Moss website saying one way or the other.
