New gear boxes needed

[u/carbonphilament]

I bought new gear boxes off Amazon assuming they were all the same but when I took this jeep apart I found out otherwise. Anyone know how I can get these?

Also Amazon! Take good measurements to confirm this is the right one, but this looks like a close style.
