Herb,
People will argue this point all day long but we have always found that if
the chassis rails as well as the inner sills, outriggers and floor pans that
all work as a semi-unibody team are healthy, the weight of engine and
gearbox should not change things. If the above mentioned complete structure
has enough flex to make that much difference, something in that structure
"team" isn't healthy.
Obviously while changing that much of the structure, much of that unibody
team will be absent, allowing flex even if the chassis rails are okay, so
the chassis will need to be supported so it is straight, etc, and all
additions of inner sill, floors etc. will have to be maintained.
Always use the outer panels (before they are repaired) as indicators to
maintain door gaps, pillar placement, etc.

Subject: [Healeys] Restoration Question
I am in the process of restoring my Germen spec.1962 BT7, side shift tri
carb. I need to replace inner, and outer sills, and rocker panels. The
floors are OK. I will be using the original to the car, body panels and
shrouds. Now to the question. Is it necessary to leave the engine and
transmission in place when welding in the sills and rockers? Can the body
panels and doors be fitted with the drive train removed? How much does the
chassis flex with or without the drive train?
Your collective experience would be much appreciated.
Herb Miller
