More Series 1 240Z differences

[Arne]

I spent some time today cleaning in the garage, which in my case always ends up with me sorting and organizing parts. And I noticed a couple more differences between my early '71 car (aka Series 1 or 1970 production) and my later '71s (aka Series 2). In both cases below, the parts in question from 12743 (10/70) are different than the parts from either of my later cars - 27602 (4/71) and 37705 (7/71).

The first two pictures are of the glovebox lock. Note that the surface of the button of the early car is completely flat, while the later cars' buttons are concave (dished in). The pictures don't show it well, but the early car's button is also a very nice chrome finish, while the later cars buttons have a satin finish.

The second pair of pictures are of the wiper arms. The first picture shows that the early arm for the driver's side is noticeably shorter in length than the arm on later cars. The later cars' arms are both about the same length, but have a different angle from side to side. The early car's arms still have the different angle, in addition to the different length.

The second wiper arm picture shows that the early arms did not have the manufacturer's logo at the base, but the later arms do. I don't know if the early arms were made by the same manufacturer or not.

Can any one else confirm these differences?

The lock set on my 6/70 is flat as you show. The wiper arms do show the longer on the right but, the logo's are there.

Pardon the blurry pics. Grandkids dialed in my camera. These are from my 10/70. Original or not, I can't say.

The lock is not like either of your examples Arne. Although concave, the indent is smaller. No logo on the wiper arms.

Arne,

Does the one with the concave face from your later car have the two sided key or the one sided? Maybe the change in lock faces was related to the change in keys?

Probably was related, Mike. The later cars both have two-sided keys. What struck me was not just the different shape, but also the bright chrome finish on the early lock.

Here's a pic of an early NOS glovebox lock with keys.

Thanks for that, moonpup. Same flat face, same nice, shiny chrome finish.

I can confirm both on my 02/70 Z. However it was changed over to a double sided key at some point, so I can't lock the box. Didn't ever try it untill just now, and I was unaware mine originally had a one sided key.

Arne...I also have one NOS wiper arm. I think is an early one, as the packaging is the old style and it doesn't have the logo on the base. Looked on the underside and found these markings. Is there a difference on yours?

[Arne]

A correction and a picture.

Correction - I got my description wrong in the first post. The arm that is significantly shorter than all the rest is the Series 2 driver's side arm, not the Series 1.

Picture - Here is the undersides of my pair of Series 1 arms (no logos). Similar to the NOS one from moonpup.

This set is clearly marked as a left and right side, with the left side being the shorter of the two. Not only shorter but also formed with a more extreme bend on the end.

Only difference from moonpup's NOS wiper arm is the letter j on mine where as he has a t. Doubtfull that anyone would know the significance of that.

Moonpup, out of curiosity I looked up the part number in the 1970-1973 Factory Parts Catalog. For the left side, it shows 26380-E4600 to be in use up to 07/73, then it shows 26385-N3600 with a from date of 08/73. There are no earlier wiper arms listed.
