Need help on a few under car issues

Added a set of frame connectors to my Challenger. Wondering where I'll need to drill through one of them for emergency brake cable. Also, switched it over to a four speed and welded in a hump. Where do I need to weld the bracket for clutch/z bar stuff ?

If someone has pictures it would be appreciated. Need to get both of these things done before I paint the underside.

Thanks, !

Slotting the frame connectors for the cable may be needed depending on what type of connectors you use. The sawblade style ones that weld to the floor the whole way and you have to do it.

I used the US car tool connectors and yes, welded them to the floor. I'm just wondering what area/distance I need to drill the hole. I'm assuming staggering the holes so cable isn't kinked. Like to see a picture if anyone has done it.

Youll have to trial fit your cables where they will lay at
