Correct that the spreader bar is the trans cooler . . . and license plate mount.

It's thin-wall - but not too thin - tubing powdered black.
Radiation area is 120 square inches.
Seems to work well, a lot of heat comes off it.

Black is the most efficient heat radiation color as well.

I have the same setup on the 31, but it has 100-110 square inches of radiation area due to it's smaller diameter.
The Derale 1" deeper with air tubes trans pan helps as well.

Your finned aluminum trans cooler looks to have quite a bit more radiation area than mine so you can probably expect it to work quite well.

Driveshaft loop be good.
I have two on the 31.
One up front like NHRA and SCTA rulebooks say and one toward the back due to a crossmember is required for the Chris Alston Chassis Works 4 links.
Both loops are Chris Alston ovals bent to a sharp radius from 1" x 2" rectangular tubing.

Pic = front loop.
