i use a heater core out of a 1991 Ford Escort. Look it up at
www.heatercore4u.com It's kinda small but it does the job. Ford cores are usually better because they inlet and outlet are usually identicle. Chevy's usually have a 3/4 and 5/8 tube while Fords have (2) 5/8 tubes. BTW i got the core at Autozone for $29.99
