another oil sensor question

[blkmonday]

ok its time for my oil change and time to replace my oil level sensor..i picked one up at the local parts store. i have a 96 sts. its an aftermarket part made by standard auto parts. the original part is made of metal and my new aftermarket one is plastic? also i noticed the thread on the new plastic one is longer..i threaded it in a little and it felt like the plastic was cross threading a little so i pulled it back out and im wandering if this is the right part. the description says its for a 96 seville...but thats not always right. the part cost me 40 bucks! ugh! has anyone replaced one of these with a plastic one before or did i get the wrong part??

Go to www.gmpartsdirect.com and buy the AC Delco part. Much cheaper than the dealer.

F.Y.I.
i ended up stopping at the dealer. i asked the parts guy to look up and pull the part to compare it. it has been changed to the plastic unit and the standard motor part one was identical to the new factory replacement. i guess they changed over to the plastic threaded one to avoid stripping the threads on the oil pan. anyways its changed out and no more annoying "check oil level" warning at every start up. :steering
