Off subject Mike (& Kenny), but I was going to PM you anyway about my early-73 2L's doors.
Yesterday I took off inner seals to check for rust - both holed along the bottom!
... at least the friggin Longs were still good!
However, I peeked behind the inner panes (still on until I can pull the windows later after stripping the interior ofr strip/blast & repaint/repair) - & they're apparently a "new"3rd door type: "Light Late" & it's still OE from the 8/72 build date - late window regulator/etc. & late inner frame - but with no late side-impact bar welded in there!!
I know exactly what & where to look for them in there, cuz the 74 shell has them as expected, but only it's pass is clean no rust for a transplant, & the driver door has some rust but may need to fid a clean late L door.
So I guess my early 73 2L with "Light Late Doors" will gain the 110 pounds (each or total I don't recall) with a door transplant, cuz I'll never find a clean set of these oddball Late Lights anywhere!
Another oddity for your First 1000 series, at which I'll post pix when the interior panels come off later. BTW mine is VIN ...01954 on there.
