I have the OLD TL like it's not a even a TL-Plus but I'm using the diagram I found online for TL-Plus because they're pretty much identical. The only small allen screws were for that shroud thing on the top where the barrel screw into the body.
I found this one on ebay, it looks the same, but I'm just not sure.
