Motor plate thought?

I did. It's been a while but I think the red bushings are PST poly strut rod bushings.
The mounts are pieces of 2" angle iron welded together, then bolted to the frame rail (with a thick-wall tubing spacer through the rail to prevent crushing when the bolt is torqued securely.

Now, I don’t know much about anything, but was told not to use nutserts for structural applications. In keeping with my theme of not knowing much about anything, I have no clue what kind of loads would be put on that 1/4”? screw/bolt.

I also found that semi truck frames are assembled with Huck brand fasteners, which are basically big badass nutserts. I’d be interested to see engineering data on various types of nutserts, not that I’d be able to decipher any of it. :lol:
