instead of repairing a nasty dent on my 91 Z's door i can get an 87 IROC door matching color but i noticed the DOOR ground effects are not the same for those years. are they interchangeable? will it be a direct bolt on replacement, no redrilling of any holes? just swap the lower ground effect?

 

The door is the same but the ground effects holes may have to be modified a little bit.

 

make sure the new door has the same operations as the old door such as; power windows, power locks, and power mirriors the door panels will also be different i think (but what do i know im a firebird guy) but you can easily switch those

 

yea it has all the same options, different interior panel but ill just swap my old one on. i dont like the idea of more holes to drill but for the price i cant turn this down i guess
