HI Propaneburner, I own a 58 Burb and also need those rear Quarter panels. I am a long way from using them so i havn't been looking too hard, just keeping my eyes open. What i might try is 62 to 66 fleetside quarters which you can buy. They come in two pieces from the center of the whell forward and from the center of the wheel back. Not too expensive for one piece to try. I think LMC and Brothers both have these panels. If you try this please post back on here if they worked.
