Hi All,
I'm working on an '09 GT, and noticed something weird in the diagrams from Mazda, vs what my car, and other pictures I've found online are.

In my car, (which I don't think has had the arms out at all) the cam bolts are oriented such that the nuts are down, and the bolt is inserted from above the subframe.
In mazda diagrams, it shows the bolt inserted from below, and the nut above.

I am needing to replace the bolts (seized, so that's gonna be fun), but just want to check which orientation SHOULD the bolts be in?

Also, a side question, is it possible to remove/install the cam bolts from the top without having to drop the subframe?

 

The cam bolts in my car are oriented the same as yours, dropped in from the top with the nuts on the bottom. I don't believe they're removable from the top without dropping the subframe. Very little room up there unfortunately.
