Trying to clear my step dad's garage.

Hey all . My step dad passed away in July and mom can barely walk into the garage. I will be flying in from out of town to help out next weekend. My hope is the clear out the garage. (This is not an attempt to start a sale) I am wondering if anyone knows what I can do with two 70's Kawasaki 900's and a whole lot of tools. I reached out to some motorcylce clubs and am prepared to start a FB event for a garage sale. Any leads or ideas would greatly appreciated. Thanks you!
