3rd Gen LCA's on 2nd gen?

Looking to purchase new OEM LCA's to replace my worn bushings & balljoints.
By the time i order all the parts with shipping /tools / time i determined it would be easier to just buy new.
My understanding is that chassis was carry-over, however 3rd gens have different part numbers.
2012 LCA Part Numbers
Left:4806904040
Right:4806804040
2017 LCA Part Number
Left:4806904060
Right:4806804060

Interestingly enough, the 2017 OEM parts are cheaper.
Anyone have any knowledge on the differences?
Are they they the same just a new improvement / revision level?

 

Think someone had said the rear bolt assemblies on the 3rd Gen were different

 

I was about to make the same mistake an purchase a set but I was caught in time. Forgot where the thread was for a little bit but here:

 

Awesome! thanks for the help. Curious why it took Toyota 6 years to changeover.
So since I am locked into the 05-15 window.
Would it be better to spring for the 2015 LCA part number?

I am finding:
2012:
Right:4806804030 $271.75
2015:
Right:4806804040 $279.90

Thanks for the help!

Had to check link on my phone. That's awesome pricing. I will sweep ebay before I pull the trigger.
For some reason Ebay is blocked at my work...
