easy disc brake swap

[FirstGen]

Basically these are the parts I used:

1968 C20 lower control arms
1990 3/4 ton Light Duty 2X4 must have (1.25" rotors) spindles
1990 1.25" thick 6 lug rotors
1990 calipers off same truck
1990 upper and lower ball joints
1990 outer tie rods
inner tie rods MOOG part #ES2020RL
1990 style tie rod coupler


The only catch is to cut 3/4" off each end of both tie rods on each side of the truck so you can have enough room to align the truck. Well at least I had to since mine is lowered 4" in the front.

The front end I bought off the 1990 truck was 5 lug. All I did was went and bought the 6 lug rotors and bolted them on. If you wanted to stay with the 5 lug, you'd save yourself about $120 bucks.

After everything is done, you will now have 14mm studs on the front. I fixed this by drilling my rear axles and pressing in 14mm studs in the rear also but you wouldn't have to do this... I plan on going to a rear disc setup using a floating rotor design and so this helps that plan also...

Good luck.
