We had an order from a customer for an A352 shell with a 91.5" wheelbase for a Herald chassis. Here is the process we used to create this special order shell.
The extra length was added behind the doors. This is the shell before:
Chop chop!
Extra sections were laid up in the mould and then trimmed and tech screwed in place, before being glassed on the rear
Once cured the external surface and joins were ground out and filled
Moulds were taken so the process will be much simpler if required again
