You'll need to custom make it from plexi glass, that one there is for a thompson drive, but I think they can be modded to fit onto sammy's...
I started to make a full clear top but stopped moddin for a bit, i'll see if I can find the pics ina bit here.
WAYYY off topic, Ifyou go to tacobell don NOT eat the "crunch wrap supreme" and get ready for bed, it gives you reallllllly bad gas.
EDIT: It's not a great pic but its a pic:
I'll try to get some this sunday, thats the next day I have off from work.
