1967 - 72 Chevy C20 Axle Swap to 9.5", 14 - Bolt w/ Disc Brakes

How I installed a 90's, 14-bolt, semi-float axle in my 1971 C20 pickup. This swap maintains the original axle width (65 1/4") and adds 13" disc brakes. All parts are GM so will be reliable and easy to maintain. *Axle = 1988 - 2000 Chevy & GMC light duty 3/4 ton with drum brakes. 2WD and 4WD are same width if 13" drum brakes. *Disc Brakes = Early 2000's Chevy & GMC light duty 3/4 ton. Calipers mounted on back side so parking brake cables route correctly. About 63/37 bias on factory combination valve. This is way too much rear brake! UPDATE: I changed to 2003-2006 Van calipers for about 70/30 bias with original brake valve. I then installed a BAER valve in series with the original for up to 80/20 bias. This works very well and you keep your factory combination valve (anti-dive, pressure warn light, proportion)! See my brake valve video. Other necessary parts: 1. Axle perches cut for 3 3/8" axle tube 2. Laser cut brake mounting flanges (1/2" thick) 3. Laser cut backing plate concentric rings (3/16" thick) 4. 3/16" custom brake line kit and 3/16 to 1/4 adapters at distribution block 5. 2X LH brake hose from 2001 C2500 6. 2X LH parking brake cable from 2001 C2500 7. Dorman wheel studs, P/N 610-182. These are 1/4" longer than stock allowing for 1/4" wheel spacers when necessary. Notes: 1. C2500 Calipers require 1/4" spacers to fit 1973-1987 Chevy 16x6.5, as well as Ford 16x7. Else, calipers interfere with inside of rim. 2. The original brake proportioning valve results in about 63/37 with this setup. Rear brakes lock up in panic stops. 3. I later changed to 2003-2006 Express van calipers along with a BAER brake valve to prevent lockup. This also eliminated the need for wheel spacers and longer studs! See my other video detailing this change.
