    I think you're SOL on that without Inline tube. Tamraz has a MC but it doesn't have bleeders. TPP has the newer box style, but no 70 fat style.

    I hope there is an alternative even if it is eBay.

    Would the Inline tube setup work for 4 wheel disc brakes too?

    Here is my current set up with the master leaking onto the booster:

    Notice the difference in the color of the hold off valve relative to Inline Tube’s unit above which is black. The master cylinder shape, the lid and the hold down set up is different from Inline's picture above.

    The pic you posted of Inline Tube's setup is for 71+ disc brakes, if I'm not mistaken. The one you have on your car looks right.

    Guessing you are after a "bolt on system" Have five or six booster cores and three "fat" master cylinders. Non of the masters have bleeders, though and the codes on the tiny tabs on the boosters are a riddle to decipher. Doubt I have a desirable late 69 to summer 70 coded one.

    For sure they had the bleeders. I am look for bolt on. I have the cores myself. I am changing it out because the master has leaked and damaged the plating on the booster.

    This is the Inline Tube version. $85
    There catalog is wrong as it shows a 71/72 unit for 1970. Correct for Chevelles maybe?!?

    Anyways, I have both versions in stock as well as the pull off valve......

    I've mentioned to my contact at Inline Tube to change there catalog descriptions for there master cylinders but no change has been made yet.

    Buick made the change to the square style in 1971.
    I believe Chevy made the change in 70 which is what Inline Tube seems to go by.....

    Todd-- I am looking for the combo of parts depicted in post #6 above combined with the correct 70 master cylinder.

    We ( or I) can get that same combo but with the correct m.c. from Inline. And be a bit cheaper!
