LEGAL ADVISE

First the headliner was all wrong & has some wrinkles in it & it needed to be replaced. I told him that in time they would come out. All the rubber seals were falling off & needed to be replaced. Ive done many cars with the same name brand & never had a problem. I broke the LT door window, it rolls up & down hard. Has anyone ever put new window felt & seals on ? I told him things would be a little tight. A paint chip or some thing on the LT side lower fender. The rear window seal is wrong. I have used the same one on other builds. The LT rear wheel well paint has a wrinkle in it. Sent me some pictures of other things but ill be dammed if i can see any thing wrong. Just sent me pictures didnt say what was wrong. Here is the kicker i did alot of things on it for free. Just thought i was helping another mopar guy out. That will never happen again lol

one good stroke deserves another, tell him you've changed your mind and you'll agree to nothing sight unseen, he needs to bring the car to you
yes you effed up doing extra work and that can be an issue but again, he accepted the car and paid you, I bet he wasn't bitching about the "freebies" then! Don't let this sour you to helping a Mopar brother out.
now I have to ask, was there an actual written and signed contract or was it man to man handshake with agreed job and price? I ask because if it's in black and white then you may have a problem with specifics, you overstepped in one instance and possibly under delivered in the other and he may be able to get you on that. If handshake agreed then the scope of understanding can be argued because what you thought he meant and what he thought you meant can easily be misconstrued.
I get it that you want to protect your reputation and do the right thing but there are a million ways for customers to eff you over, no way would I give him $7000. Any money you give him is paramount to admitting fault so just nix that idea, you've offered to fix what he isn't happy with, that is different than admitting you effed up.
I will say it again, he needs to bring the car to you.
