They say any DOT 3 or 4 fluid will work, but it ain’t so. Some brake fluids will attack the rubber in the Quartermaster slave cylinder (see photo). I have compared the Quartermaster fluid with regular DOT 3 and 4 fluid and can tell you it is a BUNCH slipperier. The slave works much more smoothly.<div><img src="cid:5EE7DD78-1FE2-4198-9BF2-9251AEA9952E-L0-001"><br>BTW this is a Quartermaster 721 series concentric slave and throwout bearing.</div><div>Phil Gott</div><div><br></div><div><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Apr 1, 2020, at 9:42 PM, Scott Janzen via Fot <fot@autox.team.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=utf-8">I can tell you the size for the GT6 bits, if they are the same. <div class="">Studs are 7/16” x3-1/2” overall length, 20TPI. </div><div class="">My ARP box is marked 206-5404 Triumph TR7 main stud kit.<br class=""><div><br class=""><div class="">On Apr 1, 2020, at 7:58 PM, Brad Eells via Fot <<a href="mailto:fot@autox.team.net" class="">fot@autox.team.net</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hello Amici,<div class=""><br class=""></div><div class="">Thinking aloud here as I have time on my hands.
