The stamp on the back of them has a number and a R or L for right or left. 

These are 55L on top and 55R on the bottom

Looking at your pic your shorter arm has a more bend at the end than mine. Your shorter one is a 55R I think.

My shorter one says 55R but it has a lesser bend hence I ended up installing it on the left.

my other one says KE50L which is currently installed on the right. Only problem is with the longer one on the right the wiper at the far end do not stay flush alll the way down towards the far end.

Here is the gap with the longer arm on the right!

These were the two 240z wipers I picked from a guy who was throwing them away. Looks like he might not had the correct ones as well. I am thinking to keep it as is and will look for the correct 55R on eBay!!!

Unless u want to sell this pair 😊

I’d be happy to sell my 55R/L pair.  Let’s discuss the details with a personal message. I’ll send you one right now.

I recently replaced the rubber "refills" in my stock 240-Z wiper arms. The Trico 47-700 (7mm) were too loose. The 47-800 (8mm) were too tight. I took the 8mm rubber and used the 7mm stainless stiffeners and the combination fit perfectly. About $20.00 total.
