Chassis measurements?

[440Interceptor]

Hi all, I have done some initial measurements of my accident damaged 1984 280i chassis. Damage is limited to the nearside front suspension tower which is pushed back (Wheel hitting kerb hard maybe?) by around 15mm. I will be looking for a competent repairer who can pull out the steel to match the opposite side.

Question: Does anyone know whether there is/was ever a set of accurate factory chassis measurements available from TVR (to assist repairers)?

Looking at the front suspension, there appears to be little or no adjustment available apart from the anti roll bar so the chassis needs to be pretty close. What tolerances did the factory work to I wonder? I've heard 5mm.

Any knowledge/previous experiences/old measurements would be appreciated.

Thanks, Toby
