91 Stanza trunk lock

How hard is it to replace the lock on a '91 stanza? Any pitfalls that you know of? The dealer wants $150 but all I see is a couple of bolts.

if i remember properly .. you have to pop the stanza lens out to get to the lock cyl. It's not hard just make sure you take out all the nuts for the lens and get lens out with out breaking it.. then the lock cyl is easy as hell.. GL
