Nice truck! It will look great with the Macho paint/stripe scheme.
I just went through my '79. I didn't find any 'front end kits', and just bought things individually. I bought most parts through Rockauto. They'll have almost everything you need and generally can get a range of quality as well. I did shocks, ball joints, drag link, tie rod ends, wheel bearings, wheel seals, brake rotors & pads, calipers, flexable brake lines, u-joints, double cardon, steering hoses, etc. The list goes on. It's just easier than calling/driving around locally, to find the parts you need.
A pre-bent brake line kit I think I got from U-line. The engine rebuild kit I bought from Summit, along with a few engine/ transmission related parts.
I was happy with all the parts purchased, pretty good quality and correct fitment. No returns required!
