Changing drum to disc.

I would like to change the drum brakes over to a disc. I've asked a couple of buddies and one of them had said that some chevy s10 spindles will fit right in with no problems. Is this true? Are there other options for a swap?

I did the swap on my '72 and it was quite easy. I used a used disc brake set up off a chevelle(spindles, prop valve, etc) installed rebuilt master and booster, calipers new hoses, pads, bearings, bent new lines, and new discs. Done in a weekend. Of course that was 15 years ago. Now you can buy complete NEW kits soup to nuts no hassle no grease. Wish I had that then. Or you could put 1.5" drop spindles in front and now were talkin'...

GM changed the taper on the ball joint studs on the A-body cars after 1972. Later spindles will "bolt up" but the studs DO NOT make proper contact inside the spindle. This is NOT SAFE. Use the correct spindles for the car.

Is this for an Abody? If so I know someone makes a kit so you can use your drum brake spindles. I don't have the info right now but I have seen it in the past. JKaz

The only difference between the drum and disk spindles is the length of the boss for the upper caliper bracket bolt. The boss on the drum brake spindle can be machined down and the caliper brackets installed.

brake swap

I don't know what year car your are coverting, ECI makes a swap kit that moves the wheels in 1" on each side over using the 68-7s swap and 1/2" over the stock drum position. This is a necessity on 64-67 a bodys or your wheels may rub the fenders

The 1967 and 1968 A-body cars used the same four piston disc brakes (same spindles, same rotors, same calipers). Why would there be a rubbing problem with factory wheels?
