Sounds like you're taking on an adventure!

If you blindly take everything you might need, you won't have any room for anything else.

However, being prepared ain't a bad thing, but make sure to include some survival supplies in case you get stuck out in the middle of nowhere.

1 of the best things to take along is not a part or a tool and that is a repair manual for your car. So even if you can't fix it, having a manual handy may help someone else who has the skills/tools, but needs a manual because they've never worked on a 1974 140 before.

And if worse comes to worse, you might have to wait a couple of days while you source a needed part. Now that might be an adventure unto itself.

Good luck!!

If you have or can borrow a truck with a trailer hitch, rent a tow dolly and save yourself a lot of worry. Put the front wheels on the dolly and then crawl under and disconnect the drive shaft at the diff and pulling it to one side and tie it securely to the frame. I towed a 53 Healey from MA and my son towed a 71 144 from TX this way with no problems. We live in MD. Also you need no license plate on the car because you are towing it with two wheels off the ground,
You can tow at 60 mph with no problem. Just be sure to leave at lot of space for stopping. You have a lot of weight pushing you.
one more caution, after you have towed the car a short distance, a mile or less, stop and tighten the straps holding the front wheels to the dolly. Tom

That is a very open ended question. It depends on the condition of the car. Was it well maintained and driven daily or has it been resurrected from 10 years of indifferent storage (in which case put it on a trailer rather than drive it).

If the parts are original, I would be concerned about the ball joints and A arm bushings; but, if they fail that is not really going to be a roadside repair.

Is the 1974 the last of the D jet or is it the first of the K jet fuel injection systems? If it is a D jet I would bring along a service manual, a wire cutter / stripper and some wire and tape and an electrical tester in case you need to make field repairs on 46 year old electrical connections. K jet systems are not really amenable to field repair if anything goes wrong with the fuel distribution unit.

If the car is D jet and the fuel lines are original or of unknown vintage bring spare fuel line (5/16") or just replace it before you set out. It has been 33 years since I parted with my K jet equipped '79 242 GT so I don't remember much about the K jet fuel system details.

My recollection is that K jet systems run at very high fuel pressure (90 - 100 psi) and can be a little harder on the pumps than the D jet. If the system is K jet and the pump is old you might want to have a spare pump on hand because replacements were not commonly available because of the operating pressure requirements. The D jet operates at 30 psi so generic substitutions are easier to find - the only problem is getting the hose fittings to match up. If the D jet fuel pump is old you might want to have an exact fit replacement on hand. The Fuel pump from the 1980 ish vintage Nissan 280 ZX is pretty much a drop in replacement (you need to reterminate the electrical connections) for the later 2 port D jet fuel pump. Its a quality product; but, not cheap.

Good luck with it.

How many miles long will the virgin voyage be? If you can share the planned course and schedule then possibly some hospitable forum members can offer you their place(s) to pull in and make minor fixes if needed.
