I see you work on big tonka toys. You have lots of mines in the Colorado Springs area.
I installed a seat out of a 2004 Silverado in my 67 Chev pickup. It's good on width, just a little thick for a standard cab truck, I'm 6'3" tall. But I'm going to use it in my suburban when it's ready, then I can move it back further. The only thing is they have integrated seat belts so you need to reinforce the floor so the bolts don't pull through. I welded 1/8" steel plate under the cab where I bolted the seats in. The cupholder in front just cleared my Hurst ratchet shifter. I have to take the shift knob off when the car seat is installed or I can't get it into drive.
