Yes, but no hardware to install them with.
The Ford hardware could cost as much as $60
so the ones fron moss mustang are a far better deal.
Unless you want to risk re-using the one-time-use fastners. []
Plus they are USED not new.

 

You shouldnt get the GT 500 LCAs if the car is lowered tho correct?

 

Its fine if you have an adjustable UCA if you are worried about pinion angle.
It also matters how much lower that stock you are.
1" drop, an adj UCA is questionable.
2" drop, an adj UCA is recommended.

 

so then if the drop is like an inch or smaller then get adj lcas and be done with it
