this is my baby its a 1985 kenworth w900b (true)flattop sitting on a 250"wb.i have the original 3406b cat motor in it and i got the inframe done 4 yrs ago which cost me well over $20,000.it was done by a trusted caterpillar diesel engine/tractor plant near me and this truck is a working show truck in progress and to tell you the truth ,it can get expensive just like any other hobby ,you can go as high as your imagination and money will take you.my advice is to really look at the overall condition of the truck.mechanically you can still get parts for it (brakes,drums,springs..etc) as for body parts you will have to source out scrap yards and you being in the usa.there are an abundance of them but you still have to check out the condition of the parts because they could be as bad as the part you are trying to replace .i can still get most parts from my kw dealership but some i have to source out.it is fun and take your time but the end result is a great feeling .hope this helps you out ..i have been around trucks all my life so if you have any questions don't hesitate to ask
