Looking for engine cover bezel attaching parts for 2007 1.8

[BCates]

Hello: Just bought a 2007 Vibe. The plastic engine cover bezel has one nut securing it to the engine. The other nut & its stud are missing. The two rear retainers are gone as well. Talking to the local GM & Toyota dealers leads me to think new parts will be hard to find. Anyone have something to sell or advice on using basic hardware—studs & nuts—as replacement parts. Thanks.

The plastic clips on the back of my engine cover went missing also, and my mechanic simply installed some bolts that fit.

They're M6 x 1 thread. I installed some Allen head cap screws. As it turns out, bicycle caliper mounting bolts are the right thread and length. I volunteer at a non-profit bike shop and we throw those away every day. So if a bike shop is closer than the hardware store, go there.

I looked up a 2007 Matrix engine cover at https://parts.lakelandtoyota.com/p/TOYO ... 0D041.html and it offered this pic, with part numbers

There are some things I don't understand about the diagram, like why there are two different plastic retainer pins for the firewall side, or why there are two different part numbers for the longer stud, but it gives the following toyota part numbers

plastic pins for the firewall side 390467-06202 or 411237-22010
short stud for front passenger side 92122-80612
long stud for front driver side 90116-06169 0r 90116-06170
Acorn nut for studs 90176-06028

If you're missing the passenger side stud, you could replace that with just a bolt from a hardware store, it's only purpose is to hold the plastic engine cover. The driver's side stud, however, also serves as one of the valve cover bolts, so it would be good to use something that does hold down that spot of the valve cover independent of the plastic engine cover.

I'd probably avoid those plastic pins on the firewall side, they break easily, and instead either use metal bolts or just leave them out entirely

Thanks all for the helpful info.
