I don't know if you have your heart set on staying with 6 lugs or not, but the cheapest way to fix your problem is to find a junk or junky early 70s & up chevy truck that you can buy for a few hundred dollars, yank the whole front crossmember & suspension from it (as mentioned above very easy, 14 bolts & the steering stuff), then take it to the scrapper & get most (or all) of your money back.

You might even find something that someone needs hauled off & get it for free, do some digging - drive around & hunt you up a parts truck & maybe even make a little money in the process!
