318 build up

Pulled these off the net
Chrysler part # is 53009180AB. FC69907 which is a national #..
"Threee basic types of pilot bushings exist. The standard size one "A", used to be avialable as Mopar 53298, but it went away in about 1990. Luckily, the aftermarket still carries it, some part bumbers are Federal Mogul PB286HD and NAPA-Balkamp 615-1026. O.D. is 0.941."B" is the NAPA 615-1033 undersized brushing-- O.D. is 0.914 for unreamed cranks. "C" is the current Mopar "narrow" replacement, 4338859. Avoid it."

I have no knowledge as to the correctness of these PNs.
