your best bet is to buy a better looking unit from eBay with a broken screen this will give you all the parts you need for a reasonable price. in my opinion it's the way to go you will probably wind up with the whole unit for less than the cost of parts. or just pm me and I'll look to see if I have a TJ-37 torn apart at the moment i can get you the parts for.
I have a cover off of my TJ-25 that fits the TJ-37 (although if loose you need to reinforce the plastic hinge with a piece of teflon or tape to lock in tighter. Send a PM to me for the details.
