I had to do this on one side only.  There should be no fore-and-aft play of the landing gear leg between the blocks.  It took about 4-5 BID.  Came out nicely.

However, your problem is that there's not enough room, not that there is free play.  If I understand the proposed problem and solution, I would say that removing a small amount of material from the back side of the big black block (the aluminum block that bolts to the aft spar and holds the spherical bearing) is the way to go.

My only concern is that aft forces should not compromise the spherical bearing and pop it out of the aluminum block.  However, since it is captured by the block and the spar, I don't see how this could happen, even if the shoulder holding the bearing was sanded away entirely (though a milling maching would be preferable if you have one).  Besides, the gear leg would bear against the block before the shperical bearing was pushed against the spar.
