Help me id this kart

I just picked this up for 100$ off Facebook market place. I’m thinking it’s a Yerf Dog, but I’m not seeing the exact model.

I’m going to build it for my kids. It’s pretty heavy so maybe a 301 or a 420. I do want to have electric start and lights. Unfortunately it isn’t a live axel but a one wheel peel.

Any suggestions and input are welcome! 7371D5E0-23D3-45E4-BE80-BD40E1511899.jpeg 2B460CB8-A946-4D64-A24A-485587946F18.jpeg
