It is a fine art to get the bonnet/tub and doors in the right place, especially after 50 years and god knows how many Po`s messing with it.
There is also body flex and tub spread to take into account, if you watch the A frame as you drive you will see the gap changing slightly, on mine anyway.
My Vitesse A frame has witness marks even after I paid a supposed expert to do a full body alignment. In the end with careful setting up of the catch and anti burst I got it to an acceptable level and without a massive slam to shut it. There are slight adjustments to be had from the hinges etc.
Depends what you want it to be, a concourse with great shut lines or a user. Mine is a user.
