Is there any differences with the M2A2 and M2A3 Bradleys? As far as I have seen, only the M2A2 has come out in the box. If I were to convert the M2A2 to M2A3, does it require major alterations?

Shohen;

There are differences...and it would require some work. I know this topic has come up before. Try searching the forums under M2A3 maybe.

I'm suprised there isn't an update kit available from one of the resin outfits...also suprised there isn't an interior update kit(s) for the various M2 configurations or the M3s.

I'd be interested in kits such as this!

Slowly there are update sets coming out for the M2s, and I mean slowly.... Latest was replacement wheels ( http://www.blast-models.com was where I think I saw them, the reality is conversion and home made updates are the name of the game..... It's quite an extensive modification too.... As I frequently say on these occasions, why can't the plastic manufacturers just get it right the first time or give us a new mould at least, and the figures and the strange gun-barrel and interior detail and...... blehhhh.....
