If you want a late version Leclerc (RT-6/RT-8), Transkit Terre Modèles has a resin update kit that fits the Heller kit (TM018). The Heller kit gives you a pre-production Leclerc MBT. And Eduard has a PE set for the Leclerc too.
There are pictures of the completed Heller model and construction shots, showing some of the areas that need re-working at:

The Trumpeter kit is apparently a poor copy of the Heller offering... It requires special glues as it's not molded in conventional plastic. It is also a pre-production Leclerc MBT. Having said that, it can't be any worse than the 1/48 Zenghdefu kit..!
Oh, and if you want to add yet more details in the crew compartment (in case the pictures shown in the link I provided in my earlier message tantalize you), check this:
