Holden VX M90 Supercharger Shaft Size

[holden4x4]

Hi guys,

Can anyone tell me the shaft size on the end of the supercharger which the pulley is pressed onto? I'm making up a new pulley for my L67 powered 4x4, but I don't have a supercharged handy to measure the shaft size to make a hub to suit. Any info would be appreciated.

Cheers

info
M90 supercharger
The L67 engine had an Eaton 'Generation III' M90 supercharger that was belt-driven from the crankshaft by a 3.8-inch pulley. The Eaton M90 supercharger had a three-lobe, twin rotor design with a 60-degree helical twist and could displace 90 cubic feet per minute (2548.5 litres per minute). For Holden vehicles, the M90 supercharger provided peak boost of 6 psi (0.41 bar).
