Hot toys body question TTM14 vs TTM18

[ShapeShifter]

Ok just a quick question, I have the Hot Toys T1000 and wanted to make a second figure using a second body and from what I thought the TTM18 narrow shoulder was the correct one but everything fits so tight, I seen videos and others used the TTM14 and seems to fit perfect! What is the differences between the TTM18 and TTM14? I thought they were the same other than a different sculpt. Any help would be appreciated thanks

Nothing I guess?

The T-1000 body has Slim forearms.

The T-1000 body has Slim forearms.

That's it? Cause he seems taller and the jacket is like a belly top on my TTM18
