My 1990 740 Turbo Volvo (B 230F) is starting to show it's age. The pump, exhaust manifold and drivers side headlight assembly need to be replaced but spare parts are hard to find. The rest of the car is in good condition with minimal rust so buying a new car in not worthwhile. Are their good online part suppliers for Volvo's in the United States and can the exhaust manifold for a Volvo 240 work on a 740 Turbo? I have a summer photo of the Maine coast to as a reward for information.
