Brake caliper bolt lengths - longer calliper bolts?

Not sure you can, that return spring wire bit runs through a hole drilled into that spacer (the one with the circular groove), it also prevents the fork touching the spring, it seems integral to the working.

I'll could go ahead and drill if that's the norm, it's just I don't know what the 'norm' is with these things if you see what I mean.

Ah, I thought that might have been two pieces. Look again methinks you'd best leave it alone :)
