  1. Patcon. the design of that circuit also uses a separate 12 V supply that would have to be routed. I've also simplified the circuit such that it only uses the 12V coming from the original switch. i.e. no additional 12v wiring needed. This keeps it very simple to put in.
  2. That was my starting proposition. However because of the need to pulse power on both wires (for the antenna I had) before removing the green power to make it go down, I had to modify the circuit.
  3. It is a 1972 Japanese domestic market fairlady z. Yes it has a rear window demister switch and the two parking light switches. Plus the 8 track radio
  4. Instructions on how to install a new inexpensive power antenna to work with the OEM antenna up/down switch.When I purchased my 1972 Fairlady Z-L it only had the 8-track face plate and a loose antenna switch. The 8-track unit itself was missing. I purchased an old 8 track off ebay, 3d printed some parts to build a mock up unit. It does not play but cartridges can be inserted, the buttons work and it looks original. The up/down switch is secured and functional. I am in the process of putting in a secret audio head unit so that I have a radio and use Bluetooth. I wanted to replace the manual antenna with a power antenna. However new antennas operate differently. Original antenna uses two wires, power one and the unit goes up, power the other and the unit goes down.New antennas operate like this;up - power to both red and green wiresdown - power to red wire only. (however I discovered that the antenna needs a pulse to both wires first to turn it on.)I achieved this with the use of three bosch type relays, a capacitor (1000 microfarad) and resistor (10k Ohm) to provide a pulse to the green wire. The capacitor/resistor powers the third relay for about 0.5 Seconds Relay 1 and 2 for up ensure that the circuits are isolated from the down wiring. Relay 3 provides the pulse to green for down.
  5. Guillermo, I did get the info. In fact one of the members was kind enough to lend me one to make measurements. I've have modelled the externals and some of the internals in Fusion360. I am still working on the internal spring mechanism. I have a set of short arm mirrors. I will replace the arm and bullet with 3d printed versions.
  6. Great to see another one surface. Same year as mine, S30-100698, with original 2l engine. (They changed the numbering format in that year, adding an additional digit. //////0 Mine also moved to the us with a returning service man. There were a couple of different models produced; FZ and FZ-L. The L had carpets, a rally clock and an 8 track. Does yours have a clock?
  7. Plus the hood latch and radiator top bar positioning. This way a sub jug could be built that would fit over the engine (if still installed) and confirm placement of suspension tower tops, and hood setup. Cheers
  8. Great stuff. Not sure if you have it yet, but would be really interested to have the design include the hood mounting bolt holes. Thanks
  9. ...and a 3d printer that can do PLA, ABS, TETG, Nylon and flexible filaments. Happy, happy, joy joy.
  10. My laser cutter makes gasket making super quick and easy. File attached if someone needs it. I've decided to fit the newer version of the spray bar. Oil Spray Bar Front GasketV5- large.svg
  11. Mine is a 9/72 JDM FZ-L it had the top one on it. However it was broken, one of the pipes connected was loose. The the car came with a spare but it was also broken. The casting quality on the junction sections is quite poor, I ended up machining the faces flat (with a router and a jig). I tried to resolder the pieces. Reasonable / workable job. However someone gave me one of the lower ones. May use that instead.
  12. I have two types, can someone confirm. The top one is older style, bottom is newer style? Or is one type an aftermarket version?
  13. I've got both an 8 track face and a cassette player face. Interesting that the knob are at different spacings The Cassette radio is at 130mm and the 8 track at about 148mm. Kats, are the units the same width and mounting mechanism in the car?
