AAVP7A1 questions

Sory to revive this thread. But I have questions. I already got a cheap LVTP7A1 from tamiya and I want to build it as an ODS 'trax.

I’m curious to know… Now that Hobby Boss’ version is available. Can you retrofit the HB interior into the Tamiya hull? WOuld that require a serious level of modding to work?
