[Closed] Help fitting ISCG Blackspire Stinger to my Pitch

Got a s/h Stinger - fitted it fine to the ISCG tabs, except when I put the crankset back in, if I push it far enough in so there is no play in the BB, the bolt heads on the inside of the granny ring foul the ISCG bolts holding on the Stinger.

I have got it now so there is only a tiny bit of play, do I just have to live with it? I didn't get any bolts with the Stinger, and just used the ones that were in the ISCG tabs to start with, do I need to try and find bolts with a smaller head to use instead?

Any help much appreciated.
