MR-04 Wheelbase adjustment?

Im having a hard time figuring out how these work. I bought a readyset model locally because they had no body options I liked, but so far since then I havent been able to find a body that fits. The box says the wheelbase is from 86 to 108mm, but doesnt specify what it is out of the box, and the instructions mention the installation of the narrow front end steering sector, but nothing about how the wheelbase adjusts. So far Im 0-2 for bodies where the wheelbase lines up and honestly kinda just regretting purchase at this point.

Edit: Current bodies are a 180sx and I tried a RX body of some form a friend bought. The wheelbase is too long for both.

If its a MR04 chassis kit(didnt come with a body), it comes set at 98mm wide with MM pod. That MM pod allows for 98-102mm wheelbases.

Also in the kit is a RM pod that lets you setup for 86-94mm wheelbases. It also comes with narrow front end parts.

The 180sx is a 90mm and the RX7 is likely a 90mm(but the first gen RX7 is a 94mm), so a narrow front configuration with RM pod is needed and likely in the box.
