I ordered the Sierra S1 to S2EX upgrade kits....I have OLD S1's, so they don't use Phillips to screw down the crossover, but a small Torx screw....OK, I figured that out....BUT.....bigger problem....
The newer S2 EX XO board is much larger than the old S1 crossover, and the hole spacing isn't even close, like an inch wider on the S2EX Board....

What have folks done besides buy a right angle drill to screw something down?

Thanks
