Alright, i have an 86 n/a and i broke a bolt on the right front wheel, the bolt that holds the a-arm and the traction bar together. It is gone and i was wondering what grade or hardness it was to get a new one, thanks!

 

I think Mazda would be the best way to go on that. that way you have a piece of mind that it will not fail you. after all it holds 2 major parts together.
