1970 c20 front drums for dana 44

[Budweis]

hi everybody
hopefully you guys can help me with this problem.
i have a 1970 c20 3/4 ton 4x4 pickup with dana 44 differential and am having problems locating front drums. i know i could upgrade to a differential with disc but for right now really just wanting a new set of drums. the inside surface diameter appears to be about 12 inches and pads are 2 inch wide with 8 lug pattern. any help on locating this drums would surely save my life as the stress this is causing me is sure to kill me. thanks in advance
