DJM Part Numbers - Help Please

[67NCRANGER]

After tireless research around the web I'm more than a little confused. Fordification shows there are different kingpin dimensions for 67-74 and 75-79 F100s, however DJM lists two varients of their beams for 65-72 (3004-4) and 73-79 (3004-4A) F100s.

I want to order from JC Whitney (10% off and free shipping ends today) BUT all they list is Manufacturer #: DB3004-3 BUT they say it only fits 75-79. So in summary - DJM contradicts Fordification and JC Whitney contradicts DJM.

Mine is a 67 with drum brakes and I have no intention of converting to disc at this time. Can anyone tell me which part number I need?

Thanks in advance!!!

Mystery solved, sort of....I called DJM and was informed they only make ONE I-beam set (part # 3004-3) for all 65-79 models...the diff part numbers are for the front/rear kit, which includes the rear shackle and hanger...the shackle and hangers are diff from 65-72 and 73-79.
