I have had the dash out on my 83T and 86T. It was not fun. My advice to someone doing this for the first time is to get some small containers, sandwich bags, etc. so that you can mark the various nuts, bolts and screws that need to be removed and replaced. If you just throw everything in a big bucket you are in for some real challenges when the time comes to put it back in. Other than that you are right, it is just taking off a bunch of screws, nuts and bolts. Set the day aside.
Also, you did not mention why you were taking it out. I suggest that, whatever the task is, you have all the parts you need before starting. You don't want to get the dash out then wait a week for a part to come in. Best to do it all at one time while everything if fresh in your mind. Hope this helps. Good luck. John
