I see that you got Kareem's jacket. Congratulations.
A couple of things that you can do, with varying degrees of dificulty:
1) Get the front zipper replaced with a double zipper. Luckily, iirc, ToJ uses mostly stock YKK 10 zips, which are not very difficult to find, even as a double zip. Of course, you do not want anyone except for a leather jacket specialist to do this.
2) Get the length shortened. This, post manufacture, is fraught with peril. It could easily throw off the balance of the jacket, the pockets, etc.. and I would personally NOT ever recommend this. I've tried this, albeit not with a leather jacket, and it was an expensive mistake.
