Any A-Body 69-72, Chevelle, Skylark, Grandprix, Cutlass etc.. You'll need the spindles, rotors, calipers, proportioning block, master cylinder, booster. Use the calipers & master cylinder for cores & get new. Brake hoses, retaining clips & frame brackets are different also. New wheel bearings, seals & hoses.
I think the Nova, Omega, Ventura may work also, can't remember which years tho'. I'm sure someone knows.

All 64-72 A-body (Lemans, Chevelle, Cutlass, etc.), 68-74 X-body (Nova and clones), and 67-69 F-body cars use the same spindles. The A-body steering arms are different, but these bolt on so just reuse your old ones if in doubt. The 69-up cars used the more desirable sliding calipers (and before someone starts touting the benefits of the four-piston calipers, I say "more desirable" due to parts availability).

Good luck finding these parts in a wrecking yard. Restorers have pretty much picked that source clean. You might find them on Craigslist, but many sellers think these parts were made from gold. You can also get everything brand new from any number of vendors. Speedway Motors seems to have the best price.

Jake I knew I had these links saved somewhere. Joe's right about some of the Gold prices. I've seen some good Kit prices on Evilbay for complete new stock parts cheaper than what some want for old rusty crap.

The 68-74 X-body has the steering components behind the centerline of the spindle, the A body are in front.

The A-body steering arms are different, but these bolt on so they can be used on the X-Body spindles.
