I'm thinking about purchasing this particular power steering pump (GM type II) with a .661" shaft


and this 6.5" serpentine underdrive p/s pulley to mount to it

but I need this mounting adapter called a 'flange mount' which fits pumps with a .662" shaft to mount the pulley to; its a press-on type of adapter.


My question is bieng that its press-on and that theres a .1" difference in diameter, would this flange mount still fit the p/s pump shaft?

Thanks in advance,
Phoenix

 

just call PSC they should have a pulley that works with out the adapter, I used one of there pulleys when I put my second pump in place of my AC compressor

 

I already went with a specific type of pulleys to install on my car (seeing if they really add hp's ) but I'll keep that in mind if all else fails. I'm sure someone has had experience installing press-on type pulleys; bieng that the p/s pump shaft diameter is .662" and the flange mount adapter .661", can I still get a good fit?

Thanks again,
Phoenix
