I might have what you need. My interrior is coming out Very soon and my overhead is already cut for an OHC. If you make it to the Dino-Q this sunday,. well chat I'm SURE you will be able to afford it :)
You can easily just take it out of the truck, peel off the fabric, spray it with super 90, and then roll on some new headliner material in about an hour. It really is easy to do. Just dont screw up when your cutting it the second time. Also, if you just get the larger OHC it will probably cover up that hole. I got a shell I can sell you.
