Not many in this business since ASL went out, Don was really good and reasonable. I still like to look through his old catalog -
Contact Bill Hodel @ 330-833-0871. This maybe the guy that Don sold his business/inventory to, still advertises in Hemmings.
Greenhoe's Corvette lists parts, but I don't know if he rebuilds or offers that as a service or not. Worth a shot -
Regards
