The front plastic underbody plastic protector was sagging real bad so I removed it. It seems that a lot of clips fell out, pretty much all of them besides the ones at the front perimeter of the covers(s). I guess it got caught in the snow and compounded the problem and pulled more of them off. You can see that the back got chewed up. I never inpected this piece closely before so I m not sure what *type* of clips I'm missing, and which ones I *actually* need.

The part circled in blue is the part I have bolts/clips for (the ones that still remained on the vehicle)

I circled in red where I think I need clips (pretty much anywhere there is a hole)

I have also attached pics of the different clip that still where on the vehicle. I requesting your help to identify how many each I need to order and where they go

 

i believe everything you circled in red is the same clip. (what you have pictured in attachment #1).

i don't recall anything like picture #3 on my car.

as far as what you have circled in blue, the 5 front center most holes are 10mm headed bolts on my car. (the same as what attaches the oil service access panel)

then the 3 immediately on either side of these bolts are the round ones (your 2nd picture).

the remainder of the holes (cut off in picture #2) again are the clip in picture #1.

 

When I replaced a bunch of clips I just went to mitsubishiparts.net and looked at their diagrams. The show exactly what part number goes where. Just search there for the undertray pieces and you will see what I mean.

 

Try Ace Hardware, I found a bunch of the same clips there, or so close that they work fine.

 

Nice garage floor, btw. I have the same thing in blue and grey

 

All the ones in red would be your first clip pic.

 

If you have fastenal around you, can get box for decent price.
