Differences between Jango & Boba Gauntlets?

Just purchased/received a set of gauntlets (unfinished). Thought I was getting a set of Boba gauntlets, turns out they are Jango gauntlets. As far as I can tell they are basically the same with the exception of:

On the right gaunt the nozzle inlet on the top is missing.
On the left gaunt it appears the flat section for the calculator is missing.

Are these the two main differences between them. If so, can anyone reccomend a way of altering the left gaunt to add the calculator piece? Can add pics if necessary. Thanks.

Boba's ROTJ Flame unit box is narrower and longer then Jango's and I believe there may be slight cosmetic differences with the right gaunt.

the first "hump" on jango's right gaunt is longer too and it has spikes in it.
