I think I need 26-393

I think the part I need is product code 26-393. The dimensions are 2 3/8 long by 11/16 wide. I think the height is either 3/8 or 7/16, but I think 3/8. Note that the bottom edge is not smooth but has 3 sort of notches.

If you look at the piece that fits inside the other piece( the part that holds the spring), it has a R registered trademark symbol and above that an indented circle with a number 9 ( or maybe a 6 ). If,looking at the piece lengthwise the R reads top,to bottom and the number is at a 90 degree angle to that.
