Glue will not hold. Sorry, but you fucked up.
I may not have read the glute ham raise section in SS carefully enough and ordered a GHD with rollers for the front pad. Shipping costs being what they are, I was thinking I might be able to modify the front pad, but I have a couple questions.
Is the knee slide problem with the rollers due to the fact that the rollers rotate, their circular shape, or both?
Seems that one could fairly easily stop the rollers from moving with some type of adhesive, but if the shape is also part of the problem it would require and entirely new front pad.

Post pics, will Trouble-shoot
There will be welding involved. Cheaper than buying another one.
