Similar Boat
I'm in the exact same boat!! Just (well back in May) bought a 72 that I had shipped from Utah. I'm also in Morris County, NJ and am not that mechanical. Eager and willing to learn, but just not there yet...
I had to have my mechanic do some engine repair work as soon as I got it, and I had him give it the basic "once over" your looking for. He is one of the best mechanics I've ever met / delt with. He also happens to be into BOTH high performance and off roading. LOVES to work on cars - really has a passion and knack for it. Unfortunately right now he's not taking any new clients. (In fact it took him 5 weeks to finish the work on my truck and it was probably only a 3-4 days of actual labor.) He's building a new garage on his property, works another FT job, coaches his kids soccer teams and still works on cars when he can...
Just b/c of how busy my main mechanic is, and until he gets his garage built, I'm looking for a back-up shop for minor things, and I'm trying to learn as much as possible and do simple stuff.
You might want to check out Bruce's Speed Shop on 46 in Rockaway. Great people - very friendly, very knowledgeable. (They even have a chasis dyno that I'm definitely gonna put my Bad-Dawg on one of these days... Just have to iron out a few more kinks first.)
I think Bruce has at least one bay in the back of his shop so he may be able to do the work. If Bruce's shop can't or won't do the work you want done, or if it would be too pricey to have them do basic stuff, Bruce could probably recommend someone.
OK Auto is a great place. I've been there once; great people inside. Nice, friendly, knowledgeable. Was amazed by all very built the rigs parked outside...and by all the super high-end / cool parts they have in stock. I intend to go back for one of their events - esp now that I have my mule. A little far from Morris County and probably too specialized (read pricey) for just basic once over or general service work.
JMHO. Good luck and please keep me posted.
