Thanks chaps.
OK, so "Plan B" will be to modified the original tunnel cover to join the new plywood 'horseshoe'.
( As modifying the bulk head needs to be done one way or the other. )
I guess I just need to take a section out near the lip/face at the front & rejoin it.
( And cutting & rejoining is definitely something they seem to do on a regular basis on the forum "next door". )
Just don't ask me to draw it as I can barely get straight lines to work!!
Cheers, Paul.
