This is a new very high quality and correct heat riser repair kit. This is the correct style of heat riser as used on the 134L flat head motor. These are located in the exhaust manifold and are almost always stuck and break when you try to free them up. This will fit the MB, GPW, CJ2A, CJ3A, and M38. These are excellent reproductions.
Note: We carry the flapper in a different listing if you need one.
