I'm assuming you are still building your airplane? Otherwise this
modification would be a major surgery.
To my experience, the adjustments of these parts is very small, and
falls within the "fiddle-range" you would expect anyway (make it
slighltly too large and trim as needed). I'm assuming you "test-fit" the
top in order to cut these parts to their correct lengths.

This one definitely needs some changes. I used 3mm plywood to make an
insert. It is attached to the flange of the bulkhead with some bid on
both sizes. When installing the bulkhead, it is a good idea to make the
plies of BID somewhat larger so at the sides they cover both the insert
and the bulkhead.

In my situation, this one is flexible enough to fit nicely.
BTW, the mod I did was slightly different. It started as a factory
installed mod-A (bought the kit from previous owner who had all the
factory accelerated options installed) , and when changing to mod-B, I
incorporated the changes only halfway. That is; I cut half of the
firewall enlargement away, and lowered the window-section also only
half-way. I bought the special upper cowling, and also trimmed it to a
size halfway between a normal cowling and a raised cowling. Now I still
have more panel space (1.5 inch taller firewall), excellent view over
the nose (1.5 inch more window at the bottom), quite a "standard"
exterior (I found the mod-B too much "aquarium-style" but taste is
personal of course), and the windscreen in a little bit more streamlined
position than in the standard mod-B. If you would go this route, you
will need the normal windscreen, but it takes some carefull cutting and
a slight extension of the rear flanges to get it all fitted nicely.
