This is why trucks are awesome; look at all that room around the overdrive transmission.
In the pictures with the new crossmember installed and supporting the transmission, are those headers secured to the cylinder heads? Wondering if exhaust is going over the crossmember or under? Just curious.
Headers are bolted up. The passenger side will clear but the driver side I might have to get creative. My OCD will likely make me snake both pipes up close to the floor and over the crossmember. I hate seeing exhaust under a vehicle.
