standard for all cars to mount their scoring transponder in the left side pod of the car. The Galmer chassis, however, did not have room in that location. The cars of Unser Jr. and Sullivan instead had the transponders placed in the nosecone of the car. Due to the proximity of the transponder, Unser Jr.'s official race-winning margin of 0.043 seconds over Scott Goodyear in the 1992 Indianapolis 500 was deemed inconclusive. After further consideration, USAC officials calculated the true margin of victory to be narrower, at 0.0331 seconds. The official margin, however, would remain in the record book. After the 1992 season was over, Valvoline purchased the race-winning Galmer chassis driven by Unser Jr. On frequent occasions, it is used for display at various engagements.
