Looking to revive an old Tyco Turbo Hopper.

The transmitter housing has been broke and the antenna will not stay attached.
- Can we upgrade transmitters on these?

Also the right front shock/spring mount is broke off. Looks like that will take new entire lower plastic housing.

Ihaven't looked at this since i was about 10. My nephew is wanting to get it rolling again and i'm needing some help.

Thanks in advance.
