Did anyone look at the pictures in the magazine? I'm also not sure which T-case I have. What does ADD mean? As I said its a '92 4cyl. Part-time with selectable hubs baught from Lithia Toyota in Medford, OR in Feb. '92. As far as I can tell there are 6 bolts that attach the t-case to the trans, however I can't tell if there is one that goes in the top where the shifters enter.
