... Most of the SL's had C-Channel steel tongues. Just check the thickness and confirm if has 1/8" thick. You may want to see if it is bending up and all. You might be able to just site it. If it's 3/16 you should be good.
Then I would just check out the outriggers to see how many you have on both sides.
If the sides haven't buckled yet you may be good.
Definitely turn the vent around.
The center of the C-channel is 3/16".
By "outrigger" do you mean the triangular pieces of steel welded to the frame that go out to the bottom of the sides? There are 4 in front of the wheels and 2 behind.
