I put in a rear bearing kit for my dryer and it took so long to get the parts, that when i put it back together, i had a yellow plastic piece that is some kind of spacer(ithink). Not sure where it goes. Any clues?

We would need a picture to know what it is. You can post one here.

O.K. Here is the pic. Thanks

You need the model number posted so we can look on the parts web site to see what that is. It looks like a shipping part. I have never seen such a part before. I doubt that it even goes on a dryer. None of the pictures have such a part in them.

Model # is FDE336RES2

Look at: Frigidaire Dryer FDE336RES2 | PartSelect (http://www.partselect.com/AdvancedModelSearch.aspx?ModelNum=FDE336RES2&mfgModelNum=&fkMfgID=4)
You may find it on the exploded diagrams.

Yes, I already looked at this and could not find the part. I am figuring that this piece was used in shipping the unit and was left inside. The dryer seems to be working fine without it so... Thanks for your help and consideration.

It looks like a shipping part to me, too.
