Is this a bad idea?

[Eatoniashoprat]

So I've got the rear tranny mount turned around to move the suby ahead and I'm fitting the tranny in (T1) to build the front mount but the reverse light sender is hitting the torsion tube. I was thinking I could just cut into the torsion tube an inch or so to make clearance for it but also read that this might be a bad idea. Any suggestions? Is there somewhere else I could mount the sender?
