Marv Minneman no longer in business (lots of HiPos including it was a YENKO distributor), Sweeney (I know of the Buick dealer still in business so the Chev side may still be in operation), Jack Lemke Chev (1620 Market St - out of business now). Another '69 L78 'velle came out of Lemke (Lem. Blue and is owned by Gary Place now). Youngstown was bustling back then supporting the steel industry and there were lots of well paid steel workers putting down their $ on hipo cars.

Good luck

Just confirmed Sweeney Chev is open - give them a call and talk to some of the old-timers to see if they remember yr Dad's car.
