70 executive with front disc brakes
I found a 70 executive in the bone yard with a front disc brake setup. I'm not sure but I think it will fit on my 68 catalina. Can anyone conferm this before I go trying to pull them off. Thanks, John-
I need to know asap.

Yes, it should be a bolt on affair. I believe you need the spindles as well, along with the master cylinder and related parts. The one potential problem is if the disks themselves are in tough shape, replacements can be hard to find.

The discs were all rusted and banged up because there are no rims on the car. Are these discs expensive or just hard to find?

I put the '70 Executive discs on my 67 Catalina and it does fit nicely. I did it 7 years ago, and seem to remember changing ball joints at the same time. Not sure if I had too, but its a good idea to do so anyway.
Make sure you also get the Master cylinder and proportioning valve, as the brakes wont work right without them. As I learned. |

My understanding is that no one makes the rotors any more. You used to be able to go to the local parts store and get them new, but now you have to find NOS parts or good used ones.

I put on discs from a '70 Bonneville on my '68 Cat. The swap was pretty much straight forward. I have heard that Kanter will/has/might be making the rotors. Check with them about availability. Hate to send you there, they're total a$$holes; but they are the only ones with new rotors I think. Everything else is available parts wise. The ball joints are the same between the original drums set up and the '70 disc. Make sure you get the MC and the small tubing and the little valve thingy below the MC as well. I had new bearings pressed in the rotors just to make sure. Bearings/seals can be purchased from Ames, or the local AutoZoo. I was told to get the pedal assembly and push rod. After doing th eswap I don't think you have to go to this length. The rod lengths are the same, I don't know if the pedal assembly is that critical. If I was you, get them from the junker and try the swap without them first. If it doesn't work then swap the assembly, etc.
