You should be able to buy all the stuff you need from GEM: they’re a good-sized company with a good dealer network, so buying spare parts shouldn’t be a problem.
However, if you prefer, you should be able to source everything from other companies as well. You can buy key-based switches from companies like Radio Shack. Do a quick Google search for ‘KEY SWITCH’ and you’ll find plenty of options for not a lot of cash. The switch itself simply replaces the toggle switch. Simple!
The same with mirrors: you can buy mirrors from pretty much any auto parts store.
As for decals, if you prefer you could always design your own and get them printed. It’s worth shopping around for prices if you want your own custom designs because they can range from $30 to $150 for decals to cover the whole vehicle. Do a Google search for ‘VINYL CAR DECALS’ to see what is available.
The year of the vehicle is in the VIN - 10th digit.
By the way - this vehicle is under a factory RECALL! Call 866.764.0616
For good replacement parts go to www.gemcar.com/loate or NEV Service This is where you can get factory parts, switches, decals etc. A ‘simple’ key switch probably is not the same cylinder and may not fit the GEM’s Instrument Panel. I would recommend go factory! Decals could be customed if you wanted. The 3 holes above the windshield are for the factory mirror. The ‘055’ probably indicates battery power. When the key is On the car will flash between battery power percentage and speed. If sitting idle will display ‘055’ and ‘000’ probably.
