Just spoke with the lady I've been dealing with at weber. She was able to find me a handle, so I should have the parts to finish it hopefully this next week.
Just for future reference, in case anybody is interested, the parts I ordered were the lid lock support (Part #86921) $3, lid lock wire (Part #86824) $3.50, hardware for the wire (Part #80805) $1.90, and the handle with the notches (Part #80772) $8.30.
Not sure that the hardware was absolutely necessary but I figured for the cost I'd go ahead and get it so I can have an idea of how it was attached from the factory.
Also, not sure if the lid lock wire is going to work. I haven't seen anybody do it but I thought it would be nice to be able to rest the lid in it. Anybody out there tried it?
Looking forward to the finished product.
