The bulb housing in the new corners was different. It had only two prongs whereas my origianls had three. I ended up using the old ones. Not a problem, but odd nonetheless?
You will need to remove the piece off the old ones where the screww sinks into....these are the loctite clips that fill in the hole where the screw goes for a snugger fit. ...the new ones didnt have them. Not a big deal, really...but something to do before you try to do it without them :-(
The housing itself is held by 3 screws ...two in front, and the killer one in the side. That one took the longest to get back in, but all in all I did it in less than an hour for both.
If I can do it, anyone can, believe me. :-)
Thansk for your help guys
