78k miles, time for front control arms

Daily driver since delivered, April 2013, including NY winters on studded snows. I have been getting a ton of tramlining and squirming under braking this past year and I think it's time to do my front control arms.

Question - I see that there are 2 part numbers for OEM 2014 front control arms:

CR3Z-3078/3079-D for 2014 GTs and GT500s built before 7/22/13;
ER3Z-3078/3079-A for 2014 GT500s built after 7/22/13.

Both come with bushings installed.The later GT500 control arms are 10 dollars cheaper a side. Are the later GT500 the same/better or will there be any issue installing them on my 2014 GT? Thanks in advance.
I would get the correct part # for your application. The $ 20 saved won't be worth it if there is a major difference. Don't forget to replace your fasteners to. Those NY winters are hard on fasteners to. It's worth the piece of mind.
By the way, I checked. No major differences, one is a later production. The ball joints changed back in 2009 but otherwise, go by when your car was produced.
