help ID rear engine shrouds

[typ901]

can't ID the year(s) of the one with the impression on the left side.
also, when did the small port start (& end) for the other ?
TIA

One with impression is 67 or earlier. There is a difference in engine console width, so could be one of two, need some SWB help here. Other looks like 78/79 911SC, based on hole for air pump check valve. G

Because there is no clearance for an A/C bracket on the later shroud , I'm thinking it's for a '76 or '77 . I thought A/C was standard on US SC's .

[gled49]

Bottom on is definitely non A/C. Yes any air pump car 75-79. Most USA SC's came with A/C but you could order without. Still? is upper one narrow (one piece)or wide engine console (two piece sandwich welded)?

2 more pix. the bottom one here I think is SC / AC type (?)

early shroud. this one does not mate to the 2-piece sandwiched cradle.

The upper shroud in the first photo is 65/66, for the pre-a/c one-piece console. It was the only one with symmetrical screw holes.

thanks all!
while I have your attention I'm also trying to nail down a few examples of the forward pieces here;

The lower one in post #5 is 3.2 Carrera.

Forward pieces : right side without notch is '65 through '69 , with notch is '70 through '77 ? Left piece is for an MFI car .
