THIS is a GREAT subject
It depends on who did the initial inlet. This is the grey area in stock work. Call "anyone" and they all say the same thing. "Its a std BDL inlet."
-Bear with me, this'll show its relevance in a second.
Ted from ARC and I were talking one night and I jokingly told him that I need to create a word for the English language used to describe a word that is void of all tangeble meaning. A word that is effectively zero on the periodic table.
Without missing a beat, he replied with, "Kerpunkeled."
We laughed and we ran with it.
I'm here to tell you after 15+ years of inletting floor metals that BDL='s Kerpunkeled. It's a principle reason why I made the move to doing my own inletting and why I have 34 different manufacturers programmed with the full gamut of SA, LA, Xtd LA, etc on the books and turn key. The amount of work that took equates to thousands of hours on a CAM system.
I didn't answer your question worth a shit likely, but it puts some of this into more perspective.
Hope this helps.
