With all the modifications that went on, besides the surrey specific grab handles and footman loops, we need to sand the paint down to see what the bottom layers are to definitely know if that is a Surrey tub.
Let me be the first to say if you decide not to restore it as a Surrey (expensive!!) please save the Surrey components for a surrey owner. I really could use those footman loops and the grab handles if they prove to be Surrey parts. DO NOT TOSS ANYTHING yet until you have checkes with us DJ guys to see if it is a special part. They used some goofy and cheap looking brackets here and there that look like someone visited the local hardware store to buy parts..
I will post a link to this over on the DIspatcher board of Derek Redmond's CJ3B site. BA, Colin , Glennstin and Oldtime are all really knowledgeable guys who will be interested iin your new jeep!!
