Well I’ll look tomorrow but I think I have the window switch your looking for and as for the hub, contact Phil at JDM Place. We can get the Momo hubs. The store is closed tomorrow but you can call any time after 12pm on Tuesday and if the warehouse has them instock, you may be able to pick it up later on during the day.
The info is in my sig and I’ll get back to you on the window switch sometime tomorrow.
