Transfer case brace

[Silverray76]

Hey guys picked up a 79 k5 not to long ago and today my friend had come over to check it out. He gets under the truck and notices that the transfer case is loose and starts to move it rapidly which also made the trans and motor move. Also he tells me there is a part missing on the transfer case because there are 2 open slots where something needs to be. I found out that there is a brace missing. Anybody have any pics of the braces hooked up and maybe point me into the direction of where i can get one. Im afraid that something may happen like it falling off while i drive
