5 on 4 to 5 on 4.5

Here is an old Mopar Acion article that is very comprehnsive on brakes. Also, on my car it had a whole 73 V8 disc K-frame swapped in, that was a simple swap (relatively speaking). Also, on the rear it is a 69 8 3/4" with the axles and drums drilled for 4 1/2" BP. If the drums ever go past turning, I am just going to get a new set of axles and a rear disc brake kit from SSBC.
