Help, Gmod Issues Possibly

[68FBODY]

So, yesterday I performed the guldstrand mod on the LH side of my subframe only to notice the second hole I drilled toward the rear is on somewhat of a curved part of the control arm mount. I was wondering is this normal because wouldn't the integrity of the bolt head be compromised of strength being on an un even surface? I'll get some pics up shortly. I USED THE GULDSTRAND TEMPLATES I BOUGHT, SO I KNOW THE TEMPLATES ARE CORRECT.





I know the shims should help with the hump in the middle
