Am i missing a weatherstrip here at the quarter window? 

Yes, you are. 

Whats the name of this part? 

 Quarter window weatherstrip. Zcarsource.com.

Do you mean this same ones from vintage rubber?

        This is vintage rubber's equivalent of the seal.   It's actually a 280 seal, I do not think the factory installed them on the 240z.

However,  many 240's have since been fitted with them.   OEM is NLA as far as I know.

thanks. Sorry for late reply! In conclusión should I purchase the 280z seal instead?

The 280 edge seal is, I believe your only choice.

i will need two of those seals and some high quality weatherstrip high quality glue. What glue is recommended?

I've used a lot of Permatex products over the years and had no problems. Either one will do the job but I'd use the 3M adhesive. 

Ok. Thanks

asides from these 2 seals i will need the driver side door seal as due to bad weatherstrip installation the constant opening and closing of the door damaged the seal. Which other supplier in addition to Vintage Rubber and Z Car source sells a tight and snug fit seal for the driver door?
