I think paul griffin has a a transit but could be wrong
Yes i have.
I fitted a wooden bulkhead myself.
Pain in the arse to measure the shape as it curves both sides.
Anyway there is bolt holes on the transit for a bulkhead what i did was cut the shape of the bulkhead with my jigsaw.
You need to cut a section out at the top for the arm of the side door.
Put some bolts in the holes a screw right down.
Put a bit of grease on the head of each bolt.
And push the wooden bulkhead onto that.
Pull the bulkhead away and you have marks for all the bolts on your bulkhead.
Drill out these marks the so the bolts a tight fit going through.
Now remove all the bolts and put your bulkhead in and fix down with bolts.
Hope this helps.
Sorry no picks as you can't see a lot of the bulkhead now as the my tank and other stuff cover it up.
