Unfortunately the impatience of youth and lack of knowledge is not a good combination when modifying vehicles.
Not wanting to get in the middle of this discussion / debate / argument whatever it is you guys want to call it, I don't know what arrangement you had with J, and welcome you to be able to stick up for yourself and your business (i had not heard of it before until J's, your work does look good from what i've seen & have seen from other places, given the ammount of shops out there not prepared to do that sort of thing, i say good on you for at least taking this on), but I will say there are a lot of youth out there and on this forum (including myself) who do put a lot of time and effort into all aspects of the car, in my case I’m building an FB, from doing the work and researching everything I do (myself & father are building this thing ourselves in our excuse for a shed, neither of us have done a full car rebuild before or work in the industry) but we get in there and give it a go after carefully planning things out, we gain as much knowledge as possible on areas we are unsure about and we in doubt we ask questions, People like My old man & Blacky just to name a few, have been very helpful to me and i owe them alot for there assistance no matter how small or large it is...
Now I hope you and J can come to some sort of resolution to which you are both happy with, but please everybody remember before this gets out of hand (if it does) this forum is for FB / EK enthusiasts of all ages, and the aim is to be able to discuss / show/ educate etc... and not argue about our rides, if you want to do that do it in another place!
If this message gets taken the wrong way them i'm happy for the Mod's to delete it...
Cheers
