71 el camino disc brake conversion

I want to put disc brakes on my 71 el camino. I can get them at the pick a part for super cheap; if I can find a suitable donor. S10s and Caprices are a dime a dozen, for example. My allignment shop says S10s use the wrong ball joints. Maybe malibu or simmilar spindles would work? Some cars use a different tie rod, but thats not such a big deal. Changing to a 15" wheel is not a problem either. Does anyone know what will work (that I will acctually find in a yard)? Thanks.

All GM intermediates from 1964 to 1972 (Chevelle, El Camino, Skylark, Cutlass, Tempest, etc...Monte Carlo and Grand Prix 1970-72) use the same basic front suspension and hubs/brakes. There ar some slight variations in control arm bushings and tie rod end sizes.

Also Nova and Buick Apollo/Pontiac Ventura from 68-74 are the same, but you'll have to switch the bolt on steering arms side-for-side as they had the steering box behind the front wheels.

Disk brakes were available from 1967 to 1972.

Metric and S-10 will not fit, nor will 70-81 Camaro/Firebird. The 73-77 intermediates and 77 up full-size GM's use the same as the 70-81 Camaro.

Thanks. That is somewhat helpful. I already know all that except for the part about 77 full size. The question I asked was that I will ACCTUALLY FIND AT A JUNK YARD not what I can order for $500.oo out of a catalog.

I've heard that doing that will screw up your steering geometry (bump steer, I think). Your original steering arms will work just fine in their original positions, since your Elky & those Novas use the same spindle. '67-'69 Camaro/Firebird also use the same parts.

As others have noted, you will ACTUALLY FIND pretty much nothing of use in a wrecking yard. The A-body and 1st gen F-body people have picked those clean. GM changed ball joint stud taper in the early 70s when they did major model changes, so spindles from the 73-up A-body, the 70-up F-body, the 71-up full size, and the 75-up X-body (Nova et al) will not fit. Same for anything later like G-bodies or S-10s. You probably already know about the B-body tall spindle swap onto 64-72 A-bodies, so I wouldn't want to bore you. That requires expensive upper control arms.

The low-cost alternative is to have your drum spindles redrilled for the original style disc brake brackets. The upper bolt is different. You can get repro caliper brackets for around $40 a pair on ebay. The rotors and calipers are available at any auto parts store.
