I need your guys info and such....Heres a lil background, i have a 2000 Accord v6 ex with around 54K miles

I use to have those indiglo guages on my car and the stopped working, so i ripped them off, but it left a glue residue on it and i purchased some Goo Be Gone, but that **** is still on there so i was wondering can i go to a junkyard and rip out another accords dash and put it into mine without messing with my mileage and such?

Secondly, when i brought in my car for a oil change, i had them do the 28pt inspection and they tell me that i have 2 broken engine mounts and that its going to be 450 dollars to fix. I was wondering if there are any aftermarket mounts that are not rubber, but polyurethrane (spelling?).

And finally, my driver sound window broke, so im guessing its a regulator or a motor or something that is broken, how much should that cost to fix and is it easy to replace or fix so i can do it myself? thanks for your help guys.
