hey guys i am going to be ordering the tailpan (part #38-7984) from lmc for my 89 jimmy this week sometime. i was wondering if that part is the actual support for the tailgate or is it just a cover and i have to fab up some sort of support? also do i need to buy the tailgate posts to get it to fit correctly (they are ****ty anyways)? i seen in the tech section this guy replaced his tailpan but put 2"x3" piece of sq. tube in first. do i need to do this? i searched ALL the previous posts on the subject but couldnt find my answer. makes me feel like its a dumb question but id rather ask a dumb question than waste $300 on some parts i dont need.
