Nice Looking Car there Steven,
I am sure you will have a lot of fun with that one.
For the Fail Safe - Check e-bay as they are £9.99 on there and with the buy it now option so you won't break the bank with that !!
This is one seller I have used and he has the failsafe's. They are a very simple bit of kit to install too.

Just type Fail in the search box on the top left and they will all come up.
Regards.......Mark
