Request for Picture - '55 2nd Series Front Bumper Bracket
I need a picture of a long side front bumper bracket as-installed. I have the brackets but I had filled the mounting hole when I boxed the frame.
...and yes, it's going to be interesting to get a nut on the inside of the boxed frame. After drilling the thru hole, I suppose I'll goop the nut up with J-B Weld, tape it to a stick, put it in place and use a bolt to hold it there until it nearly dries. See how nice and pretty -- and non-functional I made it? Thanks in advance,

I have those dimensions at home so I can get them.
how about using a long nut, like used on threaded rod, accessible from a through hole in the frame from the outside, like a hole was drilled right through, then enlarged to fit a nut through. |

Interesting idea on the long nut. We'll see once I dig in...

Re: Request for Picture - '55 2nd Series Front Bumper Bracket
here are a few pics, sorry, the square was upside down so you get metric. google can help translate if required.
looks like 2" apart though. I think the bracket is supposed to attach to the inside of the channel. you may have some messing around to get the brackets to fit a boxed frame. might be worth fabbing some new brackets or simply cut the boxing out of that area. |

looks like 7/8" in from the front edge of the frame and the 2 holes are midline in the frame channel.
help? |

You're right about the small (center) bracket attaching on the inside of the frame. It appears they did that so they could tolerate a larger radius in the bend.

Re: Request for Picture - '55 2nd Series Front Bumper Bracket
I've been pretty busy working on body prep for paint but I did get around to fixing this problem this morning.
When I looked into the frame I realized that the weld I had put in to close the hole had left a really bumpy welded surface. Gluing a nut inside the frame was out of the question, so I rounded and beveled some 1/2"-13 nuts to a little less than 7/8" O.D. (Pic 1). Then I cut a 3/4" hole, enlarged it with a carbide bit for plug fit and beveled it. I welded in the nut, used a double layer of tape as a grinding guide, ground it off, brush-primered and painted it, mostly for corrosion control (Pics 2-5). I dabbed the repair with a wet rag between every weld to minimize damage to the paint. I could have fully filled the bevel, but that would have risked bubbling the paint. It's plenty strong. The repaired area will easily be covered by the bracket.
