Bulkhead clearance

[Mark McKibbin]

Or has someone cut the hole as a quick and easy way to attend to a coolant leak or de-sludge the block water jacket  ?
We used to do this to 100E Fords to repair a leaking rear core plug, directly under the dipswitch iirc and then once you'd blocked it with a body plug the customer would be none the wiser...

Yes I have to confess doing similar on a DS Citroen when I cut a hole in the bulkhead to change the timing chain then pop riveted a cover and put the carpet back, saved me about 2 days work. The car had terminal rust and I was broke so it worked.
