Just happen to have mine right here by my Mac...
The cross-member Arthur described is "Cross-member, radiator protection",
part number 208639. It is bolted onto the very front of the chassis,
isn't a structural part of the chassis, and doesn't really support the
radiator. It's just meant to protect the bottom of the radiator from
damage. Occasionally it even succeeds at doing that...
It sounds to me like the cross-member Alan uncovered when he pulled his
engine is the actual front cross-member of the chassis. It is welded
between the side rails just below the suspension towers, and is very
definitely a structural member. The factory Spare Parts Catalogue doesn't
list it as a separate part, so presumably you couldn't order it by itself.
The part numbers for the bare chassis are as follows:
304856 Through commission number CT4387 (disc wheels) and CT4689 (wire
wheels).
305719 From CT4388 (disc wheels) and CT4690 (wire wheels) through
CT20063.
305984 From CT20064 through CT23382 (LHD) and CT20265 (RHD).
306502 From CT23383 through end of TR4 production.
I don't see a part number "C-1" or anything close in the "Chassis Frame"
section of the catalogue, nor is it in the numerical listing at the front
of the catalogue.
