70 78 Datsun 240Z 260z 280z 4 Speed Transmission Shift Knob Topper in Green Nice | eBay

I measured mine 1 1/16. So if the green is that size I'm going to buy. Wish someone made reproductions. $25 seems like a lot. It's the first one I've found in a month of watching.

The one you are looking at is the one I purchased form Baddoor250 (RUSSELL HIMLEY) the seller on 3/22/2013.

It seem odd that he would have two used ones that he found under the seat.

If you can get it it should fit, mine is like new. Good luck.

The later metal cloisonné style maps are slightly smaller in diameter than the earlier plastic ones. Maybe an eighth of an inch or so?

If you try to use the cloisonné style on your wood knob, there will be a small ring gap around the outside edge. If you try to use a black-n-white plastic style in your black plastic faux leather knob, it might not fit into the hole. You might be able to force it in, but I've not tried.

According to what El said his is 1 1/16 inches.

The green is 1 1/16 inches like the one I purchased and is 1 1/16 inches.

Bonzi measured his 73 4 speed at 27mm or 1.095

And 1 1/16 = 1.0625 = 26.987mm < 27mm so it should fit.

I just measured my red 5-speed pattern to be 1.050 OD. I don't have one of the earlier plastic patterns here to measure, but I did measure the recessed hole in a wood knob to be 1.080.

I don't know anything about the ones offered from ebay.

So, it's be as much of a difference as I mentioned above, but it might be enough that you'll have to fill the gap to keep it from looking funny.

So the general consensus is it will fit.

I had the same issue with my car. Got lucky and another member happened to have a spare.

I think I saw your post. What year car do you have and what insert did he send you?

I have a '73, and its the black and white cap you see in mgoods pictures.

Seller mailed me back that outside diameter is 1 1/16. Order placed.

Quick question. I replaced the gasket for my water pump due to a leak at the top of the seal. With a new gasket my old leak is gone but I now have a leak at the bottom. When I replaced the gasket there was some silicone gasket that I removed. Is it possible the water pump housing is warped? If I need to start a new thread in the help section I will.

ElCimino, make sure you take a picture of the shift map. Like I said before the one that is listed on eBay in # 13 was the exact same add and item I purchased from the same guy. It is interesting that the guy would have found two under a seat.

Just saying.
