I have a replacement panel that I can either cut to carry out a full repair or turn the repair panel into a removable access panel?
It would appear that having an access panel to the top of the IRS was standard at one point:

Is the additional effort (thinking of nuts and a neoprene seal) worth the reward of an access panel? It would have been useful for the previous owner.
Just interested in the form ms opinion?
Thanks. R.
