Outer Limits 4x4 Board

After an exhaustive search here and other sites ie ih8mud I can't find what length bolts I need for a 2" body lift on a 40 Series. Don't tell me to measure the ones I pull out because I don't have the vehicle to pull the bolts out of and the vehicle is about 2 hours from anywhere that will sell what's required. I need to be a good boy scout and go prepared.

100mm high tensile bolts available from bunnings for about 4 bucks each also grab a few washers to suit the diffrent mounting points on the chassie
