Your pix of the donor front end and others are eerily similar. I replaced the front clip on my 69 A56. Exactly what you are doing except I got my donor piece with the T-bar crossmember intact. I did this OVER 10 years ago before I had a digital camera so I'll have to scan the pics I have. Probably not until next week.
My 69 is an original Northern OH car, fastback, T7, A56, 340, 4 spd, factory 3.91, bench seat, rallye dash and wood wheel, manual steering and drums. Original 45K miles but the front rails completely rusted through and EVERY panel on the car was dented/creased except the roof and deck lid when I got it. It also had taken a hit in the left front. Wish I could say the car is done but it ain't. After I got my 68 driver, the 69 went to the back burner. I'd start a resto thread but everyone would be asking about updates and that'll be awhile.
