Greetings from the new guy

[matts70chevy]

Just wanted to say Hello. I'm a new member redoing a 1970 1/2 ton shortbed(actually a father son team effort). We've never done anything like this before, so we're looking for all of your expertise. Currently we are switching over from a six lug setup to 5 lug (front disc conversion) using parts from a junked 72 1/2 ton. The rear end went pretty well, but I just learned today that the front spindles from the 72 have different size ball joint holes (smaller) than the 1970 has. Suggestions? Thanks in advance for everyone's help.
