This roof rack is made from steel, brazed together. It has adjustable PETG cross braces that can slide forward or backward, and holes spaced for scale item attachment. It has aluminum lightbar brackets (included but not installed) that adjust up and down, and I have a PETG printed LED lightbar available as an option. Other 5" lightbars should fit, but I havent tested them.
 
It will fit the RC4WD Mojave single cab and the Tamiya Toyota single cab.
 
Includes 2mm hardware for the Rack, and 2.5mm hardware for mounting to the cab. You will need to drill 4 holes in your cab to mount it. It uses 2mm screws into the crossbars.
