Welcome to MLU.
Good luck finding an I.D. number from an engine number. If the upper vertical armour in front of the driver has been replaced, and the data tag removed from the divisional wall, the possible three remaining numbers may provide some information for you.

The engine may have been replaced, but the upper and lower hull numbers are most likely original. The upper hull number is located on the upper facing, gunner side of the divisional wall angle iron. The number will appear about where the back of the gunners head would be when the gunner is seated. The lower hull number is located on the angle iron above the left track guard where the upper rear protection plate fastens. See your image.

Judging from the head lamp style, is your carrier a standard U.C. No.1 MK-I*, as made in Windsor, Ontario, Canada by Ford of Canada in late 1941 or early 1942? Note the fitting for a track adjusting crook on the glacis plate, and fastening hole for a horn.

The seat cushions are filled horse hair, covered in a cotton cover, then placed inside a leatherettecover with four or five domed snap fasteners. The seat back cushions are of similar material. The seat bottoms and backrest dimensions are available, as is the information for the silencers. Seat backrests measure 25-1/2" x 14-1/2 inch. E-mail sent.
