I also posted the part numbers for the remaining 4 59* 9.200 deck R3 blocks in the system in another post....

P4876381AB (1)
P4876791AD (2)
P4876792AD (2)

one part number is Siamese bore, one isn't.

the single 6381AB is the last 48 degree block. 9.0 deck, dry sump only, no motor mounts, steel 4 bolt caps.


...and those R4 wedge blocks have some crazy low deck heights!
