    So part of my quarantine kit arrived, a 4 wheel disc conversion, so come on weekend. Got the 'complete" kit but will soon see how many other things I will need to purchase. I really don't think I have ever bought a complete kit for anything.
    Patiently waiting on the machine shop so I can have some go for this new whoa.

    Good luck. What rear wheels are you using, factory Buick chrome 15" wheels or something aftermarket?

    Yea, I seem to be needing some luck with this. Started with the rears and the brackets went on well but the rotor hat is smaller than the axle flange so something has to be machined.
    Will be using some aftermarket wheels but am in a bind there as well, I bought some wheels from a member here but they are not going to fit as the disc conversion changes fitment....me and my bright ideas.

    The axle face needs to be turned down to fit inside the rotor hat. It doesn't take much. Pull the axles and about any machine shop can fit the axles to the rotors. I've heard some folks take a grinder to the axle as you rotate it around.

    Milwakee machine shop worked just fine, as states it didn't take much.

    Just a note to all. The kit that Inline Tube sells is the same kit,but they supply a rotor that will fit over a factory axle shaft. Not sure if they have it machined,or if it is actually a different part,but the difference in price is worth it.

    I used the Inline Tube kit on mine and didn't have any issues with the rotors fitting on either the stock axles or the Strange 33 spline axles I have now. I did, however, have to grind quite a bit off the rear calipers to fit my 15"x8" wheels with 5.5" BS. In the end I don't feel like the car stops any better than it did with just front disc/rear drum. No worse, just not any better. Oh well, at least they look cool.

    I didn't have to grind the axles much at all to get them on. The 14" factory wheels do fit but just barely clear the caliper. The only reason I am doing this is because, well, I think the 4 wheel drum brakes look silly behind some nice wheels. I really really hate working on drum brakes as well.

    Going to tackle the front today.

    My 71 GS was a non-power 4 wheel drum car. My 70 Stage 1 is converted to power 4 wheel discs.

    The 71 drum car would stop but the chances of locking a wheel were much higher and the effort much greater to stop at all. I converted it to power front discs and it stops much better but will still lock a wheel in a panic stop.

    The 70 4 wheel disc car stop so much better than the 71 in either configuration and it will just barely start to slide a rear tire in a panic stop. It will throw you through the windshield easily.

    I agree. Drum brakes are a Rube Goldberg device of cables, brackets, pistons and levers in a loose formation that often stops a car on a good day. I never really mastered he art of getting drums setup properly. Discs are so simple and so easy even a caveman could do it.
