I'm not sure which version of WIS you're using, but the version I use (WIS-net) has plenty of information on the 107 chassis. If you want the most complete work instructions though, try to find a set of the MB Service Microfiche System. Back in the day, this was the best source of information for disassembly/assembly, technical specs., known issues, etc. MB apparently agrees, since its' still available to Startekinfo subscribers.


P.S. Yes, WIS is not exactly user-friendly! It takes some time to figure it out. The best way is to simply use it a lot.
