I don't see issue either and agree that a potential buyer brining up it was a 4dr are definately wanting to beat down price, otherwise if they were turned off by it they wouldn't even be trying to buy.

But, all being said I called and asked dmv their opinion out of curiosity.. Basically told not a problem, leave as is or come pick up a form, have it inspected and verified by officials and they would change title to reflect it now as a 2dr. So went and picked form up, had inspected and received many compliments on car and now car registered as 2dr and new title on way reflecting the same.

Did run into one issue that was quickly changed into a non issue. Officer mentioned while going over car he noticed the VIN plate was missing it's rivets and started to raise a stink. Had to inform him the early b bodies had VIN plate spot welded in place versus rivets and holes were for alingment only. His comment, wow I learned something new today.
