ISO a 68 red corvette racecar ( vin # 194378s426516)

hello new to the forum. my son and i are looking for a 68 corvette my dad and my uncle raced in the late 60's and early 70's. the car was owned by my uncle dave walter. it was used in hillclimbs, autocross, and road racing. the last we saw it was in 2011-13 range. it had been restored to look like it did when it was raced. it was red coupe with a white stripe that split and covered the rear bumper. any help locating the car would greatly appreciated. thanks in advance.
