Ordered 2 last week from two different vendors. First one had run out. Went to install today and the first is different from the second. The "arm" is much shorter. Its gloss black and has a "P" on the back of it. I double checked the boxes and all the model numbers were correct. Could a "Perrin" somehow get mixed into it?

 

 

of course i have the car all apart when i realize this. Can anyone that has these confirm which one is correct. the bottom one sits too far back by the dash. I'm assuming its the model for the r53?
