New member with my first post. Looking for used parts (Snapper model 21405P)

Hi, new member here. First post. I have a older model Snapper self propelled mower that I was given to me. The mower is missing the transmission speed control lever from the gear box and the longer rod that runs up the left side handle. I looked online and everything that I need is still available except for the long rod that runs up the left side handle. My question is, does anybody know of any used mower junk yards that may have my needed parts. I do know that the part number for this rod is 7023795. My mower is a 4Hp Briggs and Stratton with a model number of 21405P. If I can buy the complete lever assy. used that will also work for me. Eric
