I have a 65 k-10 frame which I believe is all original running gear. From what I have researched this should have a Spicer/Dana44 under the front end. It is a closed knuckle axle and I would like to upgrade from 11" x 2" drum to a disk brake setup. Has anyone done this or do you know if it is possible without a complete axle swap? Is it really worth it to switch? Currently the truck is full manual (steering, brakes, trans) and gets a little cumbersome to drive. I would like to upgrade to power brakes and prefer front disk. I am also having trouble finding power steering since my linkage is set up for a pitman arm from the side of the steer box and not the bottom as the 70's power steering boxes offer. Any suggestions?
