Hawker Hurricane parts help

I’m hopefully going to start building an original set of Hawker Hurricane engine mounts, I have all original tubes and some of the joints. Unfortunately I’m missing the following

1 x V joint
4 x X joints
2 x Y joints outer
2 x Z joints outer
Once complete I will be attaching to an original centre section

Can anyone assist with the sourcing of these parts.
I have some spare Hurricane joints to trade and various Spitfire bits as well
