Thank you for your help...... know that I'm sure its a 48 3100. The question isdhe has lots of rust and rotted out cab corners, kick panels and even the rear of the cab...the steps are gone, no engine, tranny, all the glass is broken except the rear and both corners, no VIN. ..there is inches of rat turds in the cab......rebuild or part out what is good? I would love to rebuild but is it more practical to just move on to another?
