1971 HLS30-14938 "Lily" build

Dash all stripped down

Pad fell in two when it came off the frame

Now for my next challenge is the dash harness. I'm really starting to dislike PO'ers. The dash harness has lots of hacks in it.

There appear to be 3 different dash harness from 9/70 - sometime in 71. I have other dashes I could use harnesses from but I don't know if they would work. Can anyone give me details on what changed and how hard adapting a 71 dash harness would be?

Pretty sure all early Z’s had higher oil pressure gauge, someone probably swapped it out with a later one.

I believe it was the really early cars, like pre 9/70. I believe my car is later than that

I think I would lay that harness out on a board and go through it from one end to the other. Check every connector and bulb. Once you get it laid out it isnt quite as daunting. When I got mine all back together, I was having an issue. It turned out to be one terminal on a connector at the passenger firewall was pushed out of place. I was panicked it was something deep under the dash!

I have a box of gauges, and maybe a partial dash harness. Let me know if you need anything. Great progress!

140lb gauges were still used in 1/71 cars.

According to my notes, the use of the 140psi gauge ended as of "1/71", somewhere around VIN 020000.  This implies that the installation of the 90psi gauge began in Feb-1971. 

FWIW, the lowest and highest VIN's that I've seen for a 1/71 Z are, respectively, 018482 and 020500. That VIN range should be considered approximate (my VIN database is by no means complete), but the high-end number (which would align with end-of-month builds for January) is ~ 5000 units later than Lily's VIN of 014938 (11/70?) and coincides with a time when Nissan's production rate for the Z was ~ 2500 units/month.

There were a lot other changes made to the car's detail design and equipment at the same time, but the "1/71" change date might have been a bit fluid from one item to another so that Nissan could use up existing inventory for the various affected parts.  However, it seems unlikely that any of these changes would have pre-dated "1/71".

Just as another data point, my HLS3016511 made in 12/70 had the 140lb gauge.

So I have a question. What year is this dash?

And what year is this panel?

[SteveE]

My 8/72 matches that dash

oil pressure gauge is from an early car.

So later dash in an early car?

This is in the "Brown Z"

Cody had suggested a great plan. Cannibalize the Brown Z for the dash harness I need and anything else so I can get Lily done for now. They are only a month apart. But I saw the dash and hazard label and then I started wondering what was what?
