SA2120FM pickup upgrade question

[twoonie2]

I currently own an Ibanez SA2120FM guitar and would like to upgrade the pickups to the Joe Satriani ones (from the JS1200 model) - the PAF Fred and PAF Joe.

My question is: do I need to purchase the F-spaced versions of these pickups or just the standard ones?

Any assistance would be greatly appreciated!

Thanks!

f-spaced for the bridge, regular spacing for the neck.
