It's my turn, 47 S10 build

[Cautrell05]

The round tubing is for bracing. When i was building the motor mounts i had the jack under the crossmember and jackstands under the frame just in front of the cab mounts. When I lowered the jack i watched the distributor move almost 1/4” away from the firewall just from flex in the front rails. That wasn't going to work for me. All the tubing is 1.5" .125 wall. With an 8pt x brace under there combined boxing the rest of the frame should make it as rigid as I need. The motor is only in the 450hp range and I'm not running it down the strip.
The transmission mount hangs from the ears in the middle. I got lucky and measured right and was able to just flip the mount around when switching from the 700r4 to the 4l80 during the current rebuild. I had about 3000 miles on it to shake everything down so i would be pretty good to go.
