That looks great, Lloyd. I'm glad to see that it can be done. My 67's original UO radiator has 3 holes on each side of the dimple evenly spread out, in addition to the square and rectangles near the ends, so I want to keep the rails.
Speaking of UO, in addition to the UO tag found on the larger tank, I also found a much smaller rectangular metal tag (approximately 1/4" x 3/4") clipped on the left side of the radiator's narrower tank that was hidden under the fan shroud's side and has the letters 'CA' embossed on it. I'm not sure what that identifies.
Thanks for the replies and PM's!
Mike
