Is the battery tray and the coolant reservoir one piece? How do you get it out? I need to replace my battery tray.

 

4rth gen?

if yes, then yes, one piece

to remove, pull the battery, look under where the batt was, you will see 1 or 2 bolts, remove them, undo the hose off the rad, then pull the assembly out the top

if you were closer , I have one from a 94 z I'd sell; ya, but.......
