Yep. Same exact problem. The abs is too thick for the premium stuff to work. I tried grinding & its stil not gonna work. I've made up my mind to switch to an oem pak & lid. I scored a brand new primered lid on ebay, & I've got the bottom on order from boardtracker hd. I was just going to use the new lid on my old bottom, but nothing lines up. My old pak is as sturdy as can be, but I spent the $$$$ on the premium latches & hinges & by golly I'm gonna use em!
