Question
I own a 1991 chevy lumina car that I am trying to replace both right side doors on. The problem is I can't line them up properly. HELP!!! What does it take to make them shut correctly again. Thanks.

Answer
1st i need to know why you are replacing them. if youwere hit you may have damage to the post where they mount up at.. if you are replacing them due to rust . it all time to do it. the way we do it is mount the door in the latch 1st than bolt it up on the hinghs you will get a better line this way. do the back door 1st. the front door you may have to take the fender off to line it up right. its just a time taking job . hope this helps
