Is there a way to tell the difference between the front counterweight for one year vs another. To make it clear....if I mix the front counterweights from all the years and put them in a burlap bag, shake well, and empty on a table. Which counterweight is for which year and which is for a turbo vs a n/a?

HOZZMAN......Been there, done that. Thanks anyway. I looked at a couple of 82/83 cw that I had laying around and compared with a 87 cw and its obvious (differences)when they are compared. Don't know how obvious a 86 to a say 90 is though. No numbers on these parts so Mazdatrix site does not help. Decided to just forget this post until some other day. Just got paranoid the other day that I might have inadvertantly put the wrong cw on an engine. Decided it was not possible due to circumstances. Thanks anyway.
