What years came with the speedo that starts at 10MPH?

[er34gtt2000jp 1]

I just bought a 73 240Z and have doubts as to if it has the original (or correct) speedometer in it.

What years came with the speedo that starts at 10MPH?

Thanks

the earliest-69 and some 70 started at 20mph. not 100% sure when they switch.

just checked pics of a 73 and it starts at 0. same as my 72.

My early '71 (10/70) also has the "start at 20" speedo. As several people have noted, the '72 and '73s seem to start at zero. So maybe the only ones that started at 10 were late '71s?

My 78 starts at 10.

Did some poking around on eBay. The links below plus Stephen's post above added to my knowledge of my personal car now lead me to believe that:

'69 through early '71 (Series I cars) started at 20.

Late '71 (Series II) and '72 cars started at 0. (Edit - added info from posts #9 & #10 below.)

'73 240s and all 260/280s started at 10.

Added pictures to the thread, will try to remember to complete the collection later. Filename indicates the year.

My '73 (built 10/72) starts at 10 :-)

My spedo looks lie the one Arne posted in the for the 1973 on ebay.

Thanks for the help! I was worried that I had the wrong spedo.

My 3/71 starts at 0; don't know about my '72, it's at the body shop.

I have one 8/71 (71) and one 12/71 (72). Both start at zero.

[Arne 21]

So it looks like the late '71 (Series II) cars started at 0.

I think you've got it. My 2/71 starts at "0". Funny how they changed this stuff. Wonder why?

[Arne 21]

I recall reading road tests of the first cars, and people whined about the 'start at 20' thing. So I'm sure that was why they changed the first time. As for why they changed from starting at 0 to starting at 10? Who knows? But it probably has to do with the start at 10 being cheaper, somehow.

i don't think bill was flamin you or the car, just pointing out that with all the repair it needs, that you've got quite a lot of work ahead of you before worrying about the speedo becomes "the next step" in resurrecting this car.

I ain't flamin you or the car either.

[Fun_in_my_z 3]

Man pipe down Look at my car for starters, do i have any room to be flammin?

I think not.

Time to switch to decaph

Sorry guys I was just kidding, I know my 73' is rough and needs lots of work. I started this thread because I was not sure if I had the right speedo, not that it is going to be registering anything anytime soon though. I found it interesting that Nissan decided to put so many different speedos in the different years, or series Z's I should say. Even the 280z got a speedo change or maybe two because my 75' has different lettering than my 78' parts car!
