pix of shift cable,, looks like a Lokar,, and the dip stk is Lokar also.
seems the guy who did install cut a small notch in cross member,each side , would NOT weaken anything tho!
but if i was doing it i'd just heat the area red hot and use a ballpeen on it, but to each his own, he run the brake lines thru the holes,go figure!!
for you wanting to turbo, check out the room in front of the engine, YES lots of room.
