Well... "IF" you do, it will lower the value for someone looking for a stock tub "S" or it could raise the personal value for the current owner. These cars aren't gold mines and by the time they are (?) we would be to old to capitalize. Have fun.
Not that it is much help. But I saw a fastback at the Garland Texas Show that tubbed his car and also cut down the width of the backseat so it would still fold down. The guy was from Tyler Texas.and he did most of the re-fit work on the panels. So it has been done and I was amazed at how good it looked. He runs in the nostalgia as races down here
