    Hi,

    My 68 Skylark has the 4-piston caliper system. I already replaced both calipers twice but leakage doesn't stop.

    So I am thinking about a conversion and found these calipers at OPGI.

    Which parts do I need to update my 68 4-piston style with this Wilwood calipers?Sebastian

    Welwood disk brakes are good stuff. Helped install a set on a '67 mustang, a few years ago. Be aware that u must have 15" rims.

    Check will Willwood. OPGI makes a lot of mistakes when it comes to Buick parts.

    Why don't you have them sleeved??? I use White Post Restorations in White Post Va. They come with a LIFETIME warranty. I have been using them for yrs. NEVER a problem. I know there a little costly but then again all you have to do is replace with same kind with no kind of alterations/modifications nec.
    Just my thoughts

    Those are designed to replace the single piston on the 69-72 cars. They need the same bracket and backing plate as the 69-72 cars. I'm not sure if the spindle is the same or not. Parts are readily available to use those calipers from OPGI or Right Stuff.

    Here's two parts I think you will need to convert to those:
