That is the $2,000 question. 6 lug rear axles are longer than 5 lug stock. You will have to purchase aftermarket 5 lug axles or the another diff housing complete. As for the front, I look around and see six lug on everything newer. I did not want to drop mine, but want disc/drum for a reliable daily driver. The lower control arm (Empty/Bare) come from a C20. The control arm shaft is the same so re-use or get new as it is 50 years old, I went new. Fitment is C10, C20, P30 68-89, P30 68-98, G30 Van 70-96...remains the same. A disc brake spindle/knuckle is harvested from C1500 heavy-half 88-98, C2500 88-99 GVW 7200 (Light Duty), Lower BJ, C1500 heavy half 88-92, Upper BJ, C1500 88-99 heavy half G2500 Van GVW 7200 96-02, Outer TRE G2500 Van GVW 7200 96-02, Inner TRE Caprice 77-96, Impala 77-96, etc. TRE Sleeve 11/16" 4.25" length application Chevy 66-04 all, 12" brake hose ACDelco 18J2172, Calipers GVW 7200 Astro 90-92, C2500 88-98 LD, K2500 88-98 Fleetwood 90-92, Deville 90-93, banjo bolts, washers, brgs, dust cap, etc. Bone yard spindles $44, Rock Auto, all other $300. I have the ACDelco pads 17D369CH ceramic w/hardware. This front suspension is 1/2 - 3/4 ton up to 2002 applications and for around $360, using Pacer Wheels 187P-6883 ET-10, 8X16 sell for $110 each. Tires, your choice. The ET-10m off-set from center places the center of the tire near to zero-scrub while clearing suspension components. Brake hose will bolt on with 3/8 -24. Change the proportioning valve, brake booster and off-set bracket if needed. Other issues, purchase hub center/bore rings to support the wheels. The factory is 90mm, wheels 101.6mm. New front spindles will have smaller hub bores. It is a change to replace worn parts, using common off the self parts and install new springs...remember, it's 50 years old. Just a suggestion.
