....for the what its worth department.
I used a repop rubber gasket on my 37 pickup and it never closed good. Seems its to THICK and won't let it come down like the old cork gaskets will...but I'm sure if you (and me) would let the vent lay "normally" we can figure out just how the bolts go. I did not have this problem on my 52.
Oops, I never tried to answer your question. On my 52 the two brackets on each side of it do not move. The bolts that go through it are souppose to let it swivel.
Let us know how you make out.
