Rebuilding the front...

My '68 has some "issues" up front. It is apparent that the upper ball joint is near failing now and I'm going to have the front rebuilt. I work out of town these days so I can't do the work myself and am taking it to a local shop (who has lots of old mopar experience). However, he wants me to get the parts myself and bring em in with the car. I haven't really looked for the best solution previously and as I need to get these things ordered today I thought this group might be the best to ask.

So, who is producing the best parts these days? Is there any real advantage to going with the aftermarket control arms for a daily driver? I'm assuming nylon bushings are preferred? What's your suggestion and who should I go through?

Thanks,

Joe
