Product review (3 stars): Worked okay but orifice was wrong size for a propane range
I purchased this part to replace the front left burner on my Frigidaire GLGFS66CBA range.

The part worked okay and fit the way it should, but they never specified whether it was for a natural gas or propane range.  When I received it in the mail, I noticed that the orifice was bigger.  It came with a 1.54 mm orifice and had an "N" on one side which I presume is for natural gas.  After doing some research online, the correct orifice for a 9K propane burner is .89 mm (my original ones had a "L" for liquid propane).

I was also looking for a front right burner but of for some reason, I couldn't find a Frigidaire part number (every website I looked at kept saying it was discontinued).  I suspected that both front burners were the same so I ordered 2 of these and the piping did line up.  The only difference is that my front right burner is the larger 12K size and the correct orifice for propane would be .95 mm.  Also, the front right burner spark plug is further away but it's easy to pull the snap clip and readjust it.

Long story short, I ended up pulling the orifices out of my old burners and reused them.  It's easy to do but I could see some people hoping for a new orifice with the unit and being disappointed.  One other note, the burner is made of a soft metal, maybe cast aluminum.  There are 2 holes so you can secure it to metal flashing in the range.  These holes do not come pre-drilled.  The original burners had 6-32 hex head machine screws but they were corroded and broke during removal.  I couldn't find the same bolts at my local hardware store but bought 6-32 Phillips head machine screws instead.  I tried running these bolts in the smooth holes which worked okay but one did break off on me.  You may want to consider running a tap down in these burners first.
