Norm,
Try this.
Take a piece of corkboart and cover with wax paper.
Plave the grip panel on the cork board and, using straight pins around the edges, immobilize the grip panel.
Then, using the thick Crazy/Super glue variant, apply a small amount on the edge ar the break. Then, very deftly slide the piece to mate with the graip panel and hold in place with additional straight pins.
This is tedious but it solves the irregular shape problem.
