Need A Part # For Shifter Spring

[69 Short Fleet]

Hi guys: I need a part # or a pic and or dimensions of the spring that goes on the very bottom of the shifter (stock granny 4 speed, Muncie). The body shop lost it and when I drive the shifter and cup (the cup that goes in the very top of the tranny) come out of the tranny. I need to get this fixed for obvious reasons and don't have a clue what it looks like and would like the proper one, also is this spring a common one for most muncie 4 speed trannys I may try the wreckers if this part is discontinued, THANKS VERY VERY MUCH, Doug
