I don't have personal experience with TMI, but a buddy of mine just had a complete TMI Interior installed in his 57 Chevy Bel Air... it is f*#@ing amazing! One piece moulded headliner (eliminates the bows), bucket seats in front and rear, centre console that runs from front to back (right back between the back buckets), kick panels, etc, etc. VERY comfortable and looks killer. If you've got the coin then it's well worth it. Definitely not in my budget (the kit cost him 10k) but it puts the car at another level. He had no problems at all. He said he ordered it, it was delivered, a couple small pieces were wrong and had them swapped pretty easily, and everything was bolt it- no fabrication needed. We're in Eastern Canada (way east) and it takes a little more time to get items, but it was pretty standard compared to anything else that's shipped.
