Hello, Do you know the ID of the pilot bushing? Thanks

Willys Jeep Parts Tech:
.630 is the ID

Are these bushings steel or sintered bronze?

Willys Jeep Parts Tech:
These are bronze. Most versions being made are a combination. But ours are bronze.

Do these bushings have to be reamed or are they already sized for the input shaft? (L134 engine)

Willys Jeep Parts Tech:
These are properly sized but may need to be hand reamed after pressing in.
