I'd start there. Maybe post some pictures? Might be able to use the old posts since they are the same spacing, but the block hole on the fender looks narrower. Might need to ream it out.
I know you can use the gotoh 510 trem with the 2 1/16 spacing in the same rout for the Gotoh 510 trem with the 2 1/8 spacing.
Can you buy it from guitar center, bring it home, try it and see if it fits and then return it if it doesn't?
