That's a 73+ crossmember/suspension. Note you have rubber control arm bushings and they didn't bother drilling the hole that does not line up. There were two different front brakes, either 1.25" rotors or 1.00" rotors, same bolt pattern etc. from 71-79 were the 1.25 only then in 80? The standard brakes became the smaller 1.00 and the old standard equipment 1.25 is commonly referred to as HD or heavy duty brakes. Measure how thick your rotors are and then you will know which parts to buy.

The frame number you gave is on the side, we need the numbers on the top. Near impossible to see with the cab on in that location. Look here (pic) the first number is the year, mine is 7 (67). Also you can see my upper control arm shaft bushing. These are original style solid steel threaded bushed ends. It rotates on threads. See how big that nut is with the the grease zerk on the end? That is what they should look like. No problem running the newer stuff lots of people prefer it.
