I think they are worth it pesonnally. The patch panels are not that hard to do if you have a shop to put the beast in. I replaced all the same panels you have stated are bad on my 52 GMC Suburban. It took some time but I was working on it on weekends and evenings after work when time was available. What part of Missouri are you in. I am from K.C. area. All the panels you would need are easily available from Carters or Chevy Duty, both in my area. There is a guy selling some of the more unusal patch panels out on eBay too. He makes a few then posts them there. The quality looks great. I am watching for some of his stuff currently. I also know of someone else looking for a panel in the K.C. area if you don't snatch up the one you refer to here.
