US CAR TOOL Frame Connector Questions

^^^^^ Like he said, and great pics
In mine I made the holes oval about 1" high and 2-3" long
Prepare to do a ton of grinding to get them to fit flush to the floor. I spent hours getting them just right.
On the driver side I notched out a 1" space where the brake line passes through and just left the line in place
Pass side I put a hole through cross frame straight off the end of the frame tie and ran fuel line straight through, clipped to inside of frame rail. I think there may have even been a small hole there already but I'm running bigger steel braided fuel line
Also, make sure the full weight of the car is on all 4 wheels when welding them in, otherwise the chassis will warp quite easily.

Once they are in you will love them. Really stiffened up my car a bunch
