Porterbuilt c notch question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was installing my c notch yesterday and the spring bolt hole or airbag stud hole in the notch doesnt line up completely with the frame?

Should I enlarge the hole in the notch or the frame?

It's the hole not circled on the bottom of the frame.

I would enlarge the hole in the frame.
Make sure you have the c-notch pulled up tight to the frame in all directions prior to drilling holes, for accurate placement.
A few c-clamps will help.

Yes I did! I lined it all up and even tried to move the upper piece to get the bottom to line up with no luck.
