This is a new very correct and very high quality exhaust manifold. This is for the 134L flat head motor. This will fit the original motor in the MB, GPW, CJ2A, CJ3A, and M38. Used ones are bad about cracking in the bend, stuck heat riser, or the header pipe stud missing or broken. These are very heavy built for long service on your jeep. This comes with an installed heat riser, and the gaskets. We have used many of these on our restorations and love them.
Note: You will have to install the heat riser spring and handle on the outside part of the shaft.
