Getting ripped off by a fellow member

I won’t be sending the intake back. I don’t want to go through the hassle of sorting out shipping to send it back and so on if I were to get a refund

as you can see in picture I took with stud in it. There’s about 3-4 thread left before the bottom of stud bottoms out. Leaving the shoulder of the stud just above the plain for the intake It’s probably possible for me to drill it a bit deeper and cut my own threads, but that leaves the chance if something going wrong. My motor skills are not what they used to be. Would if just fixed the intake I have if that was the case. Thought I was getting a deal.
Any good welder can fix that at the sellers expense.
