This is a very rare find. This is the little dust boot or seal for the jeeps with the 134F motor. This is the four cylinder Willys motor with the four intake valves in the head. These were bulk packed in G758 packaging (M38A1). This is originally for the M38A1 and M170 but will fit the CJ3B and early CJ5. The inside or ID measures right at 1 inch and the OD or outside is 1 1/4″. I have test fit these in an original floor pan and they are prefect fit. These are as fresh as the day they were made, They have a little dusty powder on them from manufacture but other than that they are perfect. Don’t miss an original.
