Can't Stop 71 440 Demon

1974 A-body brakes work great. You will need the Large Balljoint upper control arms and the complete spindle ,Rotor ,Brake assembly. Very reliable and easy to maintain. You will have a larger 4.5 bolt pattern . Moser Eng. do sell rear axles with the 4.5 BP. I am referencing 1974 but it maybe 73-78 just not sure.

Thanks for the info, I had heard this before but didn't know what all needed to be purchased or sourced (was thinking I could hit a salvage yard).
Only thing is there is the cost of new front rims. I have the bigger bolt pattern axles in the rear and have the smaller bolt pattern in the front (since it worked fine when I started)
At least I know what to get of I can't locate calipers
