I don't know if your '94 has the same brakes as the older models , but Johnnyboy posted a nice parts list for his 1986 complete brake job . I have not done the rear brakes yet , but I am pretty sure the brake shoes are 16.5 X 7 .
I would think you will be able to source all parts at a heavy truck shop , get a drum off and see what's in there .
If the brakes happen to be Q series it will be advantageous to upgrade to Q Plus .
