what bolts to my 80k20 205 t-case ?

On my 80 chev k 20 cast iron 205 transfer case right hand side there are 2 holes that are threaded ,it seems to me a bracket from there to the frame might go there.The chilton manual describes the r & r as removing the transfercase to frame bracket ..,but the dealer doesnt show anything listed..I see where some have 2 rods going from the torque inspection cover to the motor mounts ( my cover is cracked bad ) and I have heard tell of another single rod going from these 2 holes and up to the top rh bolt that holds the transmission to the eng ..i'd like this rod but cant find it at the wreckers ,but if i knew what it looks like I may have seen one in one of their boxes of missalaneous 4x4 parts..does anyone have a spare one for sale ? My transmission is a th400 but the rod should be the same for a th350 ( I'm not certain though) any info re this rod will be much appreciated
