So the metal and fiber yokes on the pop bumpers on my 1972 Williams Olympic Hockey EM were all cracked and broken so I bought a replacement off marco. (See the left set in the image below) However, I feel like the new metal prevents the rod and ring from moving as far down as it used to. If I look at one of my other pop bumpers, the assembly can suck in almost to the solenoid itself whereas this new assembly stops a decent bit shorter because the curved lip sticks out and hits the stop bracket. I also noticed the end of stroke switch barely "breaks" (it's normally closed and opens when the assembly moves past) with the curved metal yoke installed whereas on my older flat metal yokes, it pushed the switch open quite a bit more.
Is this really how it should be? Or should I use a flat metal yolk set like the one in the right of the picture below?
