I was thinking I might change the Off Side rear Qtr panel to a 93/94 style with the filler up the top. Mine's an 85 so I have no trouble removing it, but are the any hitches I may come across to doing this?

The reason for it is I want to make the sill takns and the main tank fill from the same spot and it would be easier to hide it all behind the QTR, and a longer straight section which will help when filling up with Hi-Flow (don't even bother atm)
What do people think?
