Hello, I have a 1956 Oliver OC3. On the right hand side of the hood, there is a panel missing. The opening measures 3&quot; x 16-1/2&quot;. I was told that owners cut these panels out of the hood to access the sparkplugs, however, the opening is not a jagged cut, it is a perfectly smooth cut as if done by a shear of some sort. The back side of the opening has a flat metal tab spot welded to the inside metal of the hood with a 3/8&quot; hole in it -- I think to bolt the missing panel to. The front of the opening would use the existing hole in the radiator side sheet cover. I was told this is not a factory opening. This panel would have had the ribs pressed in it. Could this have been a bolt in panel from the factory? Any other ideas on this? Thank you in advance.
