68 mustang Steering problem

yep you pulled the riv-nuts out. looking at the frame i see some surface rust but that's about it. you can buy replacemnet riv-nuts from most of the stang parts supplies. welding it on is an option too, if you choose to go that route, i have also seen people cut a hole in the side of the frame rail just above that area and then weld some appropriately sized nuts in the correct spot too, if you go this way make sure you weld the holes you cut out back up or a weld a piece of plating on the outside to cover them up. this is actually pretty common especially on a car with headers that has the drop bracket for power cylinder.

just get the one that you use when you use headers, it drops the cylinder down a bit. just weld the top part to your frame
