drawer slide parts

drawer slide part 1 is 2 inches long, 1/2 inch high at highest point.
drawer slide part 2 is 1 3/4 inches long, 3/4 inch high.
Need to find these parts in order to repair dresser drawer. A handyman who has done work for me in the past directed me to you for parts (for him to use to make repairs).

I've looked at the parts you recommended but can't find any dimensions for either one of them. Can you tell me length/height, etc? Thank you.
