Would you be able to say more on where exactly you had to drill holes?

Not very well. It wasnt a direct replacement so I had to modify it quite a bit to make it work. Meanwhile, I contacted Grand Design directly and had them ship me the OEM replacement. Your part worked in a pinch, but it doesnt allow for the square tube that moves the slide-out in and out. And my modification to your bracket rendered it unsafe until added support.
Do you have a question about this Accessories and Part?

Unfortunately, it isnt possible for Lippert to manufacture an RV-specific bracket, so therefore it is not surprising that in some cases some modifications would need to be made.
