I got my on a set but was curious on my tire options on the rear,looking to go bigger?

Hey guys If anyone is cutting up a shell at the moment, and would be happy to cut me out this piece if its rustfree id be well happy. http://i73.photobucket.com/albums/i203/Lunacy55/Cowlsection1_zps0158a10d.jpg http://i73.photobucket.com/albums/i203/Lunacy55/Cowlsection2_zps17489d03.jpg   If you can cut it with all the rusted bits intact thatd be even better but will settle for jut the bit under the wiper cowl. LMK how much you are after. Thanks Bryce

Like the title states, roller I was picking up doesn't have a key after all.
