Cat Ten sheet metal drawings

Hi, looking at a Cat Ten that is missing the complete seat and fenders. Looking for drawings so I can make the missing parts myself, does anyone has any?
Also, is it possible to find serialnumber on any other part of the tractor except on brass tag on the missing seat?
Regards
Erik

Numbers are stamped in/ hamered on:
Engine left side there is a flat spot with 3 bolt holes where you can mount a generator
On transmission case , left side behind left steering clutchhandel

Look to the square flat boss at left upper front on the engine block or below it in the casting, also on the right top side radiator casting. It is also stamped under the cover on trans. that the brass plate is mounted to in front of the seat. Steve Weaver may be able to help with the sheet metal. Look for him on this web site under side seat. good luck! catrjw
