ZR1 included M22, F41 (although I don't see it on the paperwork), and J56 (automatically includes PB). Also, no fan shroud and 10.5 inch clutch. The pilot 1970 going through Mecum has F41 on the paperwork and my understanding is that F41 was part of the ZR1 package. Every document I have for 70 - 72 ZR1's has F41 included.
