Not the flashiest site ever, but they sell 3 full electric conversion kits that they seem to have applied to Hondas, Volkswagens and a Geo Metro. http://www.e-volks.com/index.html
Some of the Conversion Parts Vendors you have listed sell complete kits as well. KTA's5 Conversion Kits for Vehicles from 500 to 5000 lbs. total weight.
Figured I'd link the 2 threads for anyone looking.
Mike and Shari at Electro I think may have the record for doing this the longest http://www.electroauto.com/ They offer full DC or AC kits for VW Rabbits, Porsche 914s, Chevy Sprint/Metros , Chevy S10s and also universal kits. They have a big database of patterns built up so they can custom machine an motor adapter for many vehicles without even needing your transmission. I bought their deluxe universal kit from them.
