The opto sensor by Sparky's feet on our Metallica is misaligned; not sure how. It's sitting about 1/2" too high causing it to constantly register. I've tried tightening/loosening the screws on the opto board, on the bracket that attaches it to the rail, I've tried bending, pushing, pulling, just about everything I can think of but can't get it to stay centered.
Any suggestions how to get it realigned? The first pic is the Sparky opto, second is the grave opto which sits flatly in the center of the receiver.
Thanks in advance for any advice!
