subframe + both control arms , i'd check the axle if it's not shot to **** and i'd also have a serious look at that knuckle of yours, if the upper part is crooked good luck aligning your car.
as for the front MOAR pictures - inner and tie rod end though

 

dat is one sexay diff yo

 

Buy a spindle or buy an angle grinder and try to save yours. Angle grinders are $20 at Home Depot. A Dremel won't even make a dent.

 

Ended up replacing subframe and both UCAs/LCAs. I have about 5* more toe on the rear driver side (side that got hit) than RR side. Cams were arbitrarily placed. Can you correct that much toe with an alignment? I think 2* is max on a Miata?

 

Check the spindle on that side. I bought a salvage spindle once that was bent at the bottom and gave me a shitload of toe.

 

Wow.

My old car continues to live a hard life...
