yes, very good advice with the cutting. thats what i did with mine
wish i had had some of the foam on hand when i did mine, it leans forward a little bit. the hardest part, by far, was getting all of the pins to go in the holes at the same time. i tried everything i could think of to make them perfectly straight with each other. finally i just meshed it together so as many fit as would, and kept pressure on it. i then poked at the others until i convinced them to slide in.
