This my opinion only and it has been used properly in the vintage class top
chopping. If done properly, top chopping "normally takes 2 tops from the
original vehicle. If you bring the door post down the size of your chop the
front and rear do not line up unless you are working with a straight up top.
(20's and early 30's)
This is where the extra top comes in; you recut the top across the center in
both directions and line up the front and rear "posts" This means adding 2 or 3
" across the top length and width. Now everything is in it's proper alignment.
You also need to add a piece to the door top. The top on a properly choped top
is actually larger than the original top.
In comp coupe and mod sports it may be different and you need to discuss this
with the committee chairmen discussing what I have said. Even with this style
of chop a higher windshield opening was and is allowed. My cars I have lookd at
during inspection appear to have a slant on their windshields which is greater
than stock. Good Luck
