Disc brake decision DONE..finally
The Scarebird install is really a snap. I've installed it on both my '65 Barracuda and my '62 Ford Falcon. You can use either 9" or 10" spindles, but make sure to order the appropriate kit. All you need are the Nissan rotors, the Celebrity (or whatever GM model) calipers, pads, and the Cadillac short brake lines. All of this is readily available at Napa. The only unknown cost is having a machinist modify the rotors. My machinist charged me $40.
All told I spent about $350, and I opted for good pads.
While I was in there I also installed a new vacuum booster and master cylinder. I also replaced the wheel bearings for kicks. Easy. If you're still using that ridiculous single reservoir jelly-jar master cylinder, get the hell rid of it. You'll need a proper disc/drum master cylinder anyway. You might factor this into the overall cost.
I've done it. I've done it twice. Easy both times. Any project can have hidden costs depending on the state of your existing gear, and how much "well as long as I'm in here" budgeting you wish to expend. But overall there really isn't anything terrible lurking in the corners.
