Default identify driver and pasenger upper cotrol arm

Ready to re-install the upper and lower control arms, but want to ensure I get this right. Looking down on the upper control arms, how do you identify the driver side UCA from the passenger side?

The outside edges should curve downwards.

The triangular shape should be offset towards the rear of the vehicle on both sides.

EDIT: I just noticed your user name , what I wrote is C3 tech. 1962 corvettes I think are differant

The front edge is longer than the rear. Ball joint is farther back

Thanks all - I just want to get this right.

Just to be sure - this pic was taken looking down on the passenger upper arm with the left hand side of the picture towards the front of the car and the right hand side towards the passenger compartment. So is
this correct? Thanks for all the replies!

looks right to me, I also think if you try to put the wrong one in it doesn't work right with the opening in the inner fender there

What year is the car? (maybe add it to your profile)

Whats going on with the 'return line? Did you 'T/Y' off the line going to the carb or have a pressure regulator? My '70 has the return directly off the fuel pump.

I used the return from the GF-432 fuel filter, the 69 pump did not have the return built in. Unfortunately, I discovered yesterday that the previous owner(s) apparently crimped off the return line! So I guess I'm going to have to replace the return line to the tank. Don't get me wrong, I love fixing my girl back up, but I really wish the previous owners would have done the job right instead of doing hokey repairs. Doesn't take that much more time to do it right and it's much better in the long run.

I will run a tap over the threads and clean them up a bit. I was just fitting the upper arm in to ensure I had the right arm for the passenger side. I'm using new hardware everywhere I can and using anti-seize on all the threads as well. While I don't have a NCRS car, I do like it to look as stock as possible.
