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.

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?
