The vast majority of the parts I use other than fabrication parts I get directly from the dealer. I'm set up so I can call in the order, they order it if needed, they call me when it shows up, I go pay for it and bring the part home.
I have worked primarily on the TJ Unlimited for the last 5-6 years. Not once have I ordered a TJJ 78 specific part in that time except for belt rails and parking brake cables. I call in, give them the year of the TJ I am working on. I don't get any wrong parts other than simple fuck-ups by me or them.
You mean they don't ask you if it's an LJ or a TJ?
