    Very dedicated to customer service and selling high quality products. This heater core is very high quality and dimensionaly fits perfect. Check the length of your original hose connections as the core I recieved had 3/4" shorter tubes. This was resolved by taking both my OE and this replacement to a radiator shop to have the original tubes transferred to the new unit. Seller was very helpful to resolve this issue. HIGHLY reccomend BestOfferCounts to anyone looking for an honest company.
