Yes, a water pump is something for sure to check... Also, replace all lubricating fluids... engine, transmission, and rear end. Also, be sure the distributor is lubricated appropriately. That is often overlooked.

Most importantly, whenever I go on a long trip (or a relatively short one), I bring along some spares. Namely, in order of importance: extra oil, antifreeze, fuel pump, distrubutor (complete with points, rotor, cap, condenser and wires installed and adjusted), coil, water pump, spark plugs... Some fuel line and filters isn't a bad idea either... and all tools needed to change any of that stuff roadside. If you aren't familiar with how to change these things roadside, you've got plenty of time to learn.

Then of course, before you go... a good overall checkup including chassis lube, tuneup, wash and wax the outside, clean and vaccuum inside, and wash the windows. A clean car is a happy car!

OF course, the more prepared you are for disaster, the less likely it is to occur. I've made several 2000+ mile trips in my '65 1800... was always prepared as mentioned above, and have never had a single problem. If you don't have all the spare parts you need, often you can find someone who is willing to loan them to you.... Or, just buy new ones. You'll need 'em someday anyhow.

As for a coin holding box... may well have been something originally optional, but I'm afraid I can't say for sure. You might have to go with "any old box"... though you'd do well to find a nice looking box to keep the car happy and feeling special...

An aftermarket dashboard fan should be easy to find...but you really shoudn't need one. Just turn them vent windows backwards and you'll get lots of fresh air at highway speeds.

Good luck! We'll hope to hear about the trip in a few months... How far is that each way anyhow?
