Nice! I'm a big fan of the old school look as well. Did you have rear leafs or coils? I definitely want to do the front disk brake/drop spindle conversion on my '68. I have leafs so I'll probably do a flip kit in the rear.
Well, my truck was a coil spring frame, but it had a lot of rust where it kicks up in the back which made the frame unusable unless I decided to back half it. So, I happened to have another frame from a parts truck that I had bought. It, however, was a leaf frame. So, I used the trailing arms, brackets and axle from the coil spring frame and converted the leaf frame to a trailing arm set up. It really isn't a hard conversion. The crossmember is already there. You just need some parts from a donor truck.
I got my front disc conversion from Brothers. It was an easy install and I had never done one before. You can use the set up from a 71-72 or 73-87 truck for cheaper, but you have to switch to 5 lug which means you have to switch the rear as well. I wanted to keep mine 6 lug.
