Parts of Different Years

Well since I got my 90-91 DB1 I have been getting it painted, but I have also bought new parts for, some of different years. What I need to know is if any of the parts I list won’t fit and what do I need to make them fit.

I bought a 92-93 front bumper, will it bolt directly on? I also noticed that the turn signals were different.

Also, I think my tail lights are a different year. I read somewhere that the 90-91 and 92-93 tails for the DB1 were different. Can anyone clarify on that?
