Notes
Penny Washer = Large Diameter washer with stated bolt diameter hole.
Setscrew = Fully threaded from under head to end.
Bolt = Part plain shaft part threaded. Must be used where radial loads exist (e.g. Suspension).
All bolt lengths are measured from under the head to the end.

http://www.namrick.co.uk/ - a good source of imperial and metric bolts, but not the trailing arm pivot bolts, for those use Steve Heath below.

As with anything TVR there may be variations!
