My whole dash board is missing!

Bodyshop owners a friend and not mad at him just really the whole situation. Secured my data tag but never even crossed my mind to worry about the vin tag/frame.
Owner said he'll cover the cost of titling if do the other dash thing but that really makes me uneasy since the body would now be different...don't want any issues with the cops. Owner also credited me some $$$ on the body work.
