LoneStarS30Z Posted January 26, 2011 Share Posted January 26, 2011 I'm guessing its from a 280Z? Quote Link to comment Share on other sites More sharing options...
dan5138 Posted January 27, 2011 Share Posted January 27, 2011 Looks like a 77/78 280Z speedo. I know for sure the 78 speedo looks like that. Quote Link to comment Share on other sites More sharing options...

LoneStarS30Z Posted January 27, 2011 Author Share Posted January 27, 2011 Thanks guys, guess my assumption was right. 2nd question then, is it plug and play into a 240z or will there need to be some modifications. I'll give it a search tonight after work. Quote Link to comment Share on other sites More sharing options...
Kevlars30z Posted February 7, 2011 Share Posted February 7, 2011 I dont think so since the 240z speedo is cable driven and the 280z is electronicly read. Quote Link to comment Share on other sites More sharing options...
LoneStarS30Z Posted February 7, 2011 Author Share Posted February 7, 2011 Well that would definitely complicate things. I still haven't found much in making a 280z speedo work with a 240z. I may just have to print and paste a new face on my speedo since I need KPH. Quote Link to comment Share on other sites More sharing options...
Kevin.pk Posted February 9, 2011 Share Posted February 9, 2011 (edited) I dont think so since the 240z speedo is cable driven and the 280z is electronicly read. The 280z speedometer is cable driven. The mechanical drive is under that paper in the second picture. The wiring plug for the lighting is probably different and possibly the mounting screw locations but I don't see why the 280z speedometer wouldn't work in a 240z with some modification. Might take a look at the trip meter reset knob thingy as well. I've actually got my dash out at the moment and snapped a quick pic of it without the paper there. If "lonestar" implies you are in Tx and in dfw, let me know, I've got a spare speedo I can throw in my car and you can see this one up close and if it would work in your car.

Kevin.pk Posted February 9, 2011 Share Posted February 9, 2011 (edited) Actually, after some very limited research... (looked for a 240z speedo on ebay) Structurally, they look very similar. The 240z speedo mounts differently. It has two mounting studs through the metal backing plate. As far as wiring that I mentioned earlier, You could probably just swap your current harness onto the 280z speedo. The lights appear to plug in the same way. The only real thing that is noticably different is the small electrical box plugs into the back of the speedo in a different spot(red wire in below picture) but has the same wires and such. The trip reset control looks to be easily swapped from your 240z speedo as well. Edited February 9, 2011 by 280zcar Quote Link to comment Share on other sites More sharing options...
LoneStarS30Z Posted February 9, 2011 Author Share Posted February 9, 2011 280zcar, Thanks a ton for info, it never clicked in my head in my pictures the mechanical drive hookup was covered in paper. The trip reset is really no big deal to me, I just need the speedo to work properly in terms of lighting up and reading speed correctly. I'm sure I can figure out mounting and lighting, but actually reading speed was my biggest concern. Also you guessed right, I'm from Duncanville, just on the southern border of Dallas. However I'm in Korea until May so unfortunately for me I couldn't reference the speedo in question to the set up in my 240z. The pictures I had posted above were from the seller.
