No, keeping quiet is keeping the peace now.

Rear upper arms are the same 90-05
Front upper arms Must be matched to the same year front upright. They will bolt to the subframe on any year. Technically only legal to stay within your age group 90-97, 99-00, 01-05. But can be used in a pinch, you can plead ignorance until someone digs up this thread LoL
Rear lower control arms are dimensionally the same. Several iterations of bracing have been added through the years. And the sway bar mount is different on 99+. All are legal on all cars.
Front lower arms: See rear lower arms above.
90-97 and 99+ have different shocks from the factory. Per SM rules, all years use the 90-97 shock.
The rear bearing, clip and seal are the same. The hub (round part with studs sticking out) are all the same except for stud hole size. 1.6 hubs use a small hole, 1.8s are larger. Either is legal, due to the 1.6 hub being no longer available from Mazda. The cast steel upright will work on any year. There are differences for ABS vs non-ABS cars that do not effect us. The 99+ uprights have large letters NC cast into the housing on the inboard side just above where the long bolt goes through. These will give a 5mm per side increase in track width. Any combination is legal.

Wow, this is confusing...just want to make sure I understand correctly regarding front/rear spindle/uprights before I get used spares. 

 

On a '99, do you have to run '99-'00 UCA and spindles/uprights?  Can't run '01-'05 hardware?  Or other years?

If you run 01+ upper arms, you need to run 01+ spindles. The ball joint taper is different from 99/00

But you can do that on a '99-'00?  I guess I don't understand the rules/how successive parts numbers work.

By the book if you own a 99/00 miata...
You can use 99/00 miata suspension parts. But the others will fit in a pinch as described above
