Re: 1975 SquareBody with front drum brakes?

SCOTI,

The information that I found online said the 73-87 were different from 63-72 and should be swapped. But as you said if they were in decent shape and I didn't have to swap them that would be even better.

I would just need to Look for the RPO code if the truck still has the label in the glove box (e.g., JB3, JB5, JB6 can indicate brake package). 1.00" rotor thickness vs 1.25" thickness.

But again since it has front drums and I would be swapping to disc I can determine that myself and purchase the proper rotors and proper calipers for the 1.00" or 1.25" rotor thickness.

I haven't even seen the truck in person yet until Saturday to see if I even want to buy it. Getting kind of worked up about nothing lol.
