I Have 4 from Williams score reels. Do you know if they are the correct? 
They look quite close from memory as i had Williams Laserball the needed some tweaking on the drop targets before but no longer have it to compare with. Must admit really bad design as you would know 
But if anybody knows if they are the right ones i will send them your way for free Regards Ralph
Hey Ralph, did a bit of googling and apparently they can be modified. PBR responded that they have none, and they were about the only hope. I've sent a PM.
