I got my first one at the bike shop.... it was some kinda weird allow and about an inch in diameter. You can buy them on ebay and get weldable steel.
Im not sure what drive shaft you have but the 3/8 is a 24 or std bmx thread axle type. The 5/16 will work if you slip the peg on then back it with the right sized nut. good luck
