i have a 64 el Camino with drum breaks and i am wanting to switch it to disk..
i know a guy that will give me a great deal if the parts will fit...

my question is will the spindles from a 71 nova fit a 64 chevelle???

They should fit. But you will need to swap the caliper brackets side to side. Otherwise the calipers will ride on the front instead of the rear side of the spindle. A Chevelle is front steer and the Nova is rear steer. You should be able to re-use your steering arm connections.
