Question about 12 Bolt Axle Tube Repair

I am wanting to restore this rear end I acquired a couple years ago. I also have a question about a number stamped on the cover surface.

First, if you look close, you can see where the axle tubes have been dented a little. I have heard about heating it up and drifting a plug through the tube to bring the material back out. I would prefer to retain the original tubes due to the stamp. The axle tubs are not bent so bad that they interfere with the axles, but I would like it to look a little better. The only guy I found so far in the region (up outside of Dallas-roughly 250 miles) said by the time he did the repair it would be almost the same as buying one of his new rear ends (typical sales pitch). Can't seem to find anyone else that would touch it, so I will have to attack it myself.

On to the next question. anyone know anything about the stamp on the cover face? It's actually a reverse stamp. Surprised to see it on a gasket surface.

I am also going to have to get some leaf spring perches to weld on....

Thanks for any info you guys can provide.

Brett........

Re: Question about 12 Bolt Axle Tube Repair

My suggestion is hammer a steel plug with metal cold.
If too much heat is applied, tube will take a set and be out of alignment.
Always seen numbers on flange and never paid any attention to them.

Glad you replied. I definitely will not use heat then. Thanks!

Re: Question about 12 Bolt Axle Tube Repair

I'd be afraid whatever is used hammering the dent out may get stuck ! lol How deep is the dent ? Think I'd recommend filler, depending how deep it is...

Re: Question about 12 Bolt Axle Tube Repair

I'll use a plug like this one. I'll machine it out of 304 stainless or 4140. I'll lube it up and get a bar that's slightly smaller than the tube and hit the bar with a sledge hammer. If I space the bar about 1/4 to 1/2 away from the plug, it will have some good momentum when I hit it with the sledge.
