Ba Xr6t antz passenger side relocation

[Mrp40l]

Hi guys first post. I have an 03 Ba and I recently purchased thr antz stage 2 Ic and cold air intake and battery relocation  kit. I was wondering if anyone has an issue with how wobbly/unsecured feeling the battery tray is as only 2 out of 3 bottom bolts lined up to be able to bolt in and 2 little bolts on the top side. Antz didn't pack screws bolts in the kit I got and I have contacted them over3 times and bolts was meant to be sent out but to no avail. So had to source some black m6 and m8 bolts from bunnings (hex top) and pursue it myself. Any ideas on strengthening the battery tray? I can post images if needed on current install
