The SR-71 Rapid Tool Express is really taking off! We get our custom chassis from the Roadster Shop—those guys know a thing or two about quality builds. Engine Master Jon Kaase delivers a one-of-a-kind engine to power our SR-71. This build is coming together fast! With the body back on, Stacey takes you through some of the other mods that are going to tie this build in with the SR-71 Blackbird.
