Mine are 5/8 in the usual positions, after drilling a pilot hole I used a step drill. 5/8 is big enough to get my pinky in to help the gravel out, glad I did it.
Exactly what I did! Then also I cut out the metal cap at the very rear of each frame rail. Next I bought a sewer snake drill type and attached 3 pieces of chain and then worked it throughout the whole side rails on both sides. The spinning chain was meant to break anything loose that could be in it. Then I raised the front up about 6 foot and rinsed it all out with hot water. After three days in my heated garage I coated it all with the Eastwood Internal Coating. Should be good for my lifetime (I'm almost 76). The complete pic was before I started.
