I have a pair of disc brake spindles for a camaro, Im not sure of the exact year but I think it might be a 77. I was wondering if it will fit my 69 chevelle. I know that they will fit a 69 nova, if that helps

do they have bolt on steering arms or are the arms cast into the spindle? If they have bolt on arms, they are the same as a chevelle and will work by removing the camaro steering arms and putting on chevelle ones. If the arms are cast into the spindle, they could be used for a "tall spindle" conversion which will need some other work. Try a search, lots of info on disc brakes here.
