Actually, you can remove the entire lock assembly without removing the
"shear bolts", with no special tools. Remove steering wheel, remove wiring,
remove plastic covers, remove clamp bolt, insert key , turn lock, Done...
I was also told these are for tamper resistance, not Anti-theft, just tamper
resistant. Being steering is rather critical....
