Exchange required, but exceptions considered for export sales. These injectors are either NEW Delphi (when available) or reman with new nozzles. Either are of equal quality. Return of matching cores within 30 days is required or a non refundable $15 per injector will be applied.
Trucks: 1982 to ABOUT 1988 used the long body injectors, but the changeover point was somewhat vague as some 1988 trucks had the new cab/body style, while others had the old body style. Using the cab/body style is a pretty fair way of telling. The long and short body injectors WILL interchange. It is the vans (all years) and turbocharged trucks that need the short injector for clearance. - JK
