72 Mustang rear shock mount busted?

[Tesla80]

What would be the correct way to fix this. I just got the car and saw this. Would welding in a patch and then re drilling the hole be the most efficient way to fix this shock mount ? Thanks in advance.

That's what I did back in the day on my 73 Mach 1, I had air shocks on it and they both ripped the upper mounts. I welded two metal patches one over each of the mounting areas and drilled new holes and it held up well for the four years before I sold the car.

Thanks that is what I think I will do.

Depends on it the metal around it is sound.

Since that area is subjected to forces both directions I would recommend putting metal on both top and bottom of the hole.

yeah I am going to make a patch for the bottom then the top and weld them both in to strengthen it up. I am also gonna check the other side to see if there are any cracks and if there are then patch that one awhile as well. Thanks again for the help.

My rear upper shock mounts were also the victim of the previous owner's air shocks. I had 12ga (1/8" thick) plates that covered the entire top of the recess (bottom of the shock mount) welded in by a fab shop. This might be overkill, but they have held up well for over 20 years. I also recommend drilling the hole after fabricating the patch and before welding. You might consider then using a bolt to hold the patch while welding.
