We've talked on a couple other threads as I'm doing the same LS conversion into a 64 Skylark conv. Man, your not afraid of much! Great job on a huge project! Cudo's to you for keeping up the build thread.
I would say I'm about where your at with the LS coversion although I don't have all the body work to tackle as you do. Love the tailights, very cool. What do you plan on doing for headlights and steering wheel? From what I'm getting from talking with Grant, you can't get a steering wheel for this airbag column.
Went to a local car show this past summer and there was a guy who took the shell of a Camaro like yours and grafted it to a 97 Firebird chassis. The car looked awesome, so I've seen that dash in an older Camaro before. He had to make up the chassis length difference in the front fenders. It was his first show and he took home a well deserved trophy.
