Some time ago, for the purposes of rebuilding the defender’s interior, I prepared a list of the necessary screws. Maybe it will be useful to someone, there will probably be some shortcomings, but it can be a good starting point.
For preparation, I used the data from https://www.lrworkshop.com/diagrams/land-rover-defender-body-chassis
In the “order” column there is a stock quantity just in case 🙂
The first table lists the commercially available bolts / nuts / washers available in most stores, below is a more detailed list with no. LR parts.
