I came across this chassis drawing on Rimmer Bros. while looking for something else.
I might send a copy of this to the "powers that be" (if anyone will ever admit it is their job
).
As it does suggest that the chassis ends at the front cross member and everything thing in front of that is a "bracket", not part of the chassis.
Note:
I'm still not going to cut anything off unless I get confirmation of this in writing.
Cheers, Paul.
