I have a feeling you need to adjust the top clips that the door panel hangs on so it can drop the panel a little. The top rails of my my 1971 panels sit lower than my 1970 panels.
The plastic guide shown here circled in red on the passenger door is missing from the driver’s side. It may have fallen inside stopping the latch from rotating fully.
It appears that it is releasing the latch (including the safety) but something isn’t allowing the latch to open all the way. A part could be broken inside the latch casing and causing the latch not to rotate fully. The investigation continues.
I got this far. Now looking into what needs to move to open it and I’ll get a coat hanger down there. If the issue is inside the latch it may be tough.
The door has a very slight sag and may be resting on the pin. It was never an issue opening from the inside, just from the outside.
Opening the door on the 71 Monte has always been a little tough but got worse this summer. I was going to look into it this fall but the door decided I should do it now. The problem is that the door won’t open now. It opens a little but still catches. I can’t get enough clearance to remove the interior door panel. Any ideas on the next step?
Small radiator. Typically a small block with no AC but some non-AC cars got the larger rad if a towing package was ordered. This was for 70 and 71 only I believe and not very common. I have not seen a 72 with a small rad. Also note that the proper rad hose is impossible to find. I buy the one for the longer rad and cut it to make if fit as best as I can.

Big block
I love that show. I didn’t realize it could be viewed outside of Canada. It appears to be a classic copper 71. That’s what the colour of my 71 looks like in the dark.
The right upper control arm for my 71 SS (12 bolt with F41) is the same as my 70 (12 bolt without F41). I also have a 10 bolt Monte without F41 in my garage but I'm pretty sure we know that control arm will not have the extra welded plate on the right upper control arm.
