You are probably better off with the factory bolts. If you do reuse those ones without the washers be sure to check the length. If they are too long they will drive into the converter itself when you tighten them and could cause damage.....potentially even a leak. I noticed in one of your earlier shots of the steering linkage that you are missing a cotter pin somewhere. I am guessing you left them out until after an alignment? Don't forget to install it / them....the helicopter engineer in me was coming out when I saw the missing pin, LOL.
