The early 240Zs ('70s and '71s for sure, '72s too, I believe) did not have fully reclining seat mechanisms. They don't flip forward either, only adjust about 10-15 degrees. Not very conducive to sleeping in the car.

OK, that sounds right. First, the Pertronix only fits the single point distributors, so that upgrade is not viable with what you are now using. Since the tach jumps when you have the problem, my guess is either some sort of intermittent connection in the wiring to the coil, or possibly the coil itself could be going bad. Start with the wiring, check, clean and tighten all connections at the ignition switch and the coil. Also check the tach connector plug. I'm going to assume that the kickdown switch above the gas pedal is still hooked up, so check connections there, and also at the relay on the inner fender below and in front of the coil.

Dual point dizzy? Is your car an automatic?

It's not as simple as it seems. The headlights are a switched ground, while the park/tail lights are switched hot. I doubt you'll be able to find a single switch off the shelf that can handle both circuits.

Blower fan is a separate fuse in a separate inline fuse holder, Dave. Blue wire somewhere behind the radio.

Typically, I've found it easiest to remove the fan and fan clutch as a unit by removing the four nuts on the water pump pulley that hold the base of the fan clutch.

Hmm, less than 60 miles away. If it wasn't the holidays I'd try to arrange a visit. FYI - no problems licensing it here in Oregon, either.

Time to learn to use the search feature, Robert. A simple search for 'xr700' gave 20 threads, and 'xr3000' came back with 26 hits. Lots of reading there.

Alan,I don't recall anyone ever claiming that the "Series" terminology was Nissan-approved or used by the factory in any way. I have always understood it to be a way to simplify keeping track of the differences in various ranges of cars. Simply a convenience. Please don't think that any of us here in the US think there ever has been anything "official" about it.

Looks like the part number may be 40343-E8800, don't know if they are still available new or not.

The only thing out of place for a 2/71 car in your list is vents in the hatch. All the rest you describe would be correct for a "late '71" car.

On slots or Libres.

I remember that Car and Driver article from reading it while I was in high school. I wish I knew where I could find a copy of it now, it would be interesting reading for those of us who want to keep their cars looking "period-correct".
