69 impala upgrades?

as I mentioned in the seat thread I made, my brother bought a 69 impala.  Does anyone know of a junkyard front (and rear possibly) disc brake upgrade?  It has front discs already, but it supposedly needs calipers and we'd like to upgrade to more readily available parts if possible.  Anyone know what if any other spindles will bolt on directly?  Outside of C3 corvette spindles.
 

This project makes me regret throwing out all my paper catalogs

More readily available than B-body stuff?

That's very hard to do.

You should be able to swap the parts (you might need the spindles too) from a 9C1 caprice (cop car) directly on to the '69. The B-body was pretty much the same from 1959 to 1990-something. Those were the biggest factory discs ever put on that chassis.

Man i dunno but i do know that 69 Impala springs are a nice upgrade for a 93 Dynasty after you cut them.. in half. 

I did an aftermarket disc and power brakes install on one once. Not sure about the factory equivalent.

69-70 apparently are their own beast when it comes to single piston rotors.  The 4 piston setup is C3.
If I went 9c1 I'd have to grab matching spindles, but then I'd want 1le rotors to maintain the bolt pattern.  9c1 spindles are physically taller than standard non-wagon spindles.  But if those would work would second gen f-body work?  I know that the b-body spindles bolt into the 2nd gen f-body.

Check carefully on swapping spindles from a 9c1 - I think (but am not sure) that one car is rear steer and the other is front steer, so they won't be compatible.  As for  the brakes there are modern disk brake kits available from several sources including Summit, just do a google on "1969 impala disk brake kit".  Be warned they are expensive...I'd keep the original ones and rebuild them as necessary, they'll work fine.

There were actually several big changes to the frames, suspensions and brakes.  Up until 1970 Chevy B body cars were unique to Chevrolet, from 1971 to 1976 things were changed so there was some commonality with the other GM lines, and from 1977 on B bodies from all GM lines were pretty much the same underneath.

I think there are aftermarket upgrades to disc brakes you can do. If I recall roadkill did that recently on their 69 crusher Impala.

I had a 70 Impala for several years. Great car but I had drums all the way around.

This is correct.  In 64, the BOP versions went to a double A-arm, but chevy kept the lower "I" arm with a strut rod for several more years. For instance, I used the stock springs from my 96 Impala SS in my 66 Bonneville along with some other parts that I forget now; maybe sway bar.  The spindles are actually from a 78 K25, but that's a different story and it was far from a direct swap.  I forget the actual year chevy switched, but I had a 73 Impala with the lower A arm.  If yours has the lower A, many parts will swap with later stuff, but you're mostly going to find small upgrades, not great stuff.

There were several years of GM A-arm cars that the drum brake spindles can be easily upgraded with LS1-era F-body rotors and calipers with a little inexpensive mods and a common bracket.  You pull the drum off the hub, machine the center of the hub to fit the smaller rotor centerbore, and it slides right on.  Then you put a spacer on the inner bearing to line up the rotor with the caliper bracket and bingo; floating LS1 Camaro brakes.
