Jason, struggling to understand what you mean by "the screws for the t-piece".
If you mean the screws that go into the little lumps that protrude into the battery tray area they should be poking through the plastic and there is enough space between them for any BRCA / EFRA legal LiPo pack to fit (i.e. less than 47mm wide).
I can't say I have ever known anybody have a problem, infact they act as a retainer to stop the rear half of a saddle pack floating about
What pack are you struggling to fit in there? Is it on one of these;

Post a pic to show us exactly what you mean if you can please.
