Re: need help on some question on front disc set up
This is the important part of the above linked thread:
67-70 truck with: 71-72 Crossmember Not Yet Installed: 1) Your truck's donor 71-72 crossmember came from the factory with disc brakes. * You can swap out the entire 67-70 crossmember in one unit. * Only a few holes will need to be drilled or elongated. * The best option is to use all of the 71-72 steering components. (centerlink, tie rods, idler arm, steering box and pitman arm) 2) 67-70 steering linkage use a different centerlink and tie rods, than the 71-72 crossmember you will be installing. 3) 67-70 tie rods are 5/8" diameter,... 71-72 tie rods are 11/16" diameter (with the opposite thread direction). * 67-70 inner tie rods are RH thread vs. 71-72 inner tie rods (that are LH thread). * 67-70 outer tie rods are LH thread vs 71-72 outer tie rods (that are RH thread). * Again,... It's easiest to just use all of the 71-72 steering linkage. * You can also use all of the 73-87 steering linkage, but you will have to change the outer tie rods to the 71-72 version to match the 71-72 spindle. 4) If you must use your 67-70 centerlink and inner tie rods: * You will be require to use a "conversion" tie rod sleeve to connect the 67-70 5/8" diameter tie rod,... to the 71-72 11/16" diameter outer tie rod. * Here is the problem: The 67-70 inner tie rod is RH thread. The 71-72 outer tie rod is also RH thread. * To correct this,... you must use a 63-70 outer tie rod in the inner location. * (The 67-70 outer tie rod is LH thread) 5) If you just want to add 71-72 spindles to your existing 67-70 a-arms,... you will need to change the 67-70 upper and lower ball joint to 71-72 upper and lower ball joints. * The outer tie rod will have to be a 71-72 outer tie rod also. (see Step #4 above) 6) Rubber brake hoses: * You must change to a disc brake style hose. * Early Classic Enterprises, and other suspension vendors, make a "conversion" brake hose that will connect the disc brake caliper, to the original 67-70 brake hose steel line location. * 71-72 hoses is another option. (but I haven't personally confirmed if the steel line connection is the correct size). * Another option is to use 73-87 hoses, (cheaper to purchase), but they are much longer, and also may need fitting adapters. * Aftermarket steel braided hoses and AN fittings is another option. 7) You can also just swap all the components from the a-arms out and leave your original 67-70 crossmember in place. * This will require you to completly disassemble both the original 67-70 suspension and the 71-72 donor suspension. * This is also a good time to clean, inspect, replace or rebuild any needed components.
