Gel Pad for pillion seat, help wanted

[brimo]

Have got my hands on a second hand seat from the states and intend putting a gel pad in front and back after carving up the foam on the pillion seat. Not having a lot of success finding small gel pads in OZ, lot's in the U.S.,
anybody know where I could find one? Being a tight arse don't wanna pay freight from the states if I can avoid it.

Not sure of anything local, maybe a bicycle shop or I think ebay might be the go. Loads of stuff on there.
