Engine Mounts

I find them at the local Autozone for very little money

Those are the rubber biscuits only...no brackets.

then I search the forums and see them for upward of $150

The $150 mounts are more than likely specific 340 mounts including the brackets. Put a wanted ad here for 318 engine mounts. Also, you need to specify whether you want biscuit style (72 and earlier) or spool type (73 and later)
