Marked up where the braces are going to land:
My scientific method for center punching holes...
Everything kind of mocked up:
Kind of hit a snag. I forgot during my engine swap days that a Ranger frame has the straightness of a wet noodle. I have the distance set about right with the front one, as you can see with two in place the slider is kicked way out at the back compared to the rocker panel... so I need to fiddle with it more to get it square.
Also played with my welder a little bit. I think it is an arts and crafts thing from Hobby Lobby or something, cranked all the way up playing on a new 3/16" plate/scrap going slow I had 0 discoloration on the back side.
It might work for tacking this... we will see. I am going to mark it with a marker too just in case it can't survive the truck ride to a real welder.
