I carefully used the original aluminum screws. Applied MB sealant to well cleaned edges pressed the covers down snug and while pressing down to seat the cover ran the bolts down carefully till they stopped. DON'T pull the cover down with the bolts. you only have about 10 minutes work time with the MB sealant. Use a couple small wood dowels in 2 screw holes to quickly guide the cover into place. Go easy on the sealant too much squeezing inside the cover can break loose over time and possibly block oil passages.
Well, everything you said applies to mine as well. I magnet tested the screws and they are steel. They are also hex head and not torx. I checked how the extra length would impact the fit, and indeed, they are too long to hold the cover in place snug. I will make this work, but I'm really ticked off that I paid roughly $25 for 5 screws that I can't even use. Do you think Chrysler will take them back?
