Initially looking at the upcoming Model Factory M2A2 ODS-SA, it looks pretty easy to backdate it to a new-build M2A2 ODS from the late '90s to about 2008ish. By that time, most units had switched to M2A3s. From just the pics, if you leave off the Driver’s Viewer camera parts on the front slope and some of the bars protecting the driver’s hatch, it becomes a standard, new build M2A2 ODS. You would also need to backdate the tracks to T157I “Bigfoot” tracks and sprockets as well.
The areas in red are what need attention. The Driver’s Viewer camera is in the circle. The raised bars around the drivers hatch (red lines) need to be removed. The anti-foul bar to the left side of the hatch (green T) needs to stay, but be mounted on the hull, not the raised bar. The rest looks good.

For an interior, you could use either a modified/updated Tamiya M2 interior with individual seating or later bench seating, depending on when you are depicting it from.
