You all seen this? Trans tunnel from uscartool

For the record..."..Frame requires substantial cutting, welding and grinding to install. A fully illustrated instructional manual is included and available for download on our main web site.
You MUST install a USCT Motorsports Level 1 Chassis stiffening kit (frame connectors and torque boxes) before installing the Transmission Tunnel Perimeter Frame. The frame connectors and torque boxes tie the factory unibody together and work with the Perimeter Frame to make your car strong and safe when removing the OEM factory torsion bar cross member center for transmission clearance.
Requires a Cross member (not included) for your specific transmission. We have them for the 727, 518, NAG1, HP70, T56 Magnum and a universal cross member, call for other applications, we will help you out."
