22 cal.savage 29a problem

i am working on a old savage/stevens 22 cal rifle and found the cartridge stop is missing. i have talked with gun parts,none available.called savage for the part or a sketch so i can make one & was told nothing available. do any of you gun owners happen to have a 29a and if so would you look inside on the bottom of the receiver in front of the trigger and make a sketch of the stop with approx sizes, it fits over a pin.i see the part in parts list but no details. thanks da whizzer WOW1930@att.net
