      Comments about National Oil Seal:

      The part was not the size of the old one.I gave all the correct info on vehicle but part was smaller than original.After some checking with helpfull clerk at local store right part was found.I believe even though it was a 2002 trailblazer the matching part was for a 2001.

          Hi Scott, glad to assist you! This is a front inner seal. To give you the correct information I would need the year, make, model and engine size of the vehicle.
