Product review (5 stars): Perfect Fit and Quick Delivery
I contacted GE Customer Service to ask them which broiler element my model JBP26WV2WW range requires.  They looked it up and said I needed a model WB44X0185 replacement broiler element, which they would sell me for $75.  I found this item on Amazon.com for under $17.

Some things you need to know.
- First, the item arrived in only 2 days -- not the 7-12 days that was estimated.  The item was well packaged, arrived without damage, and also included 2 screws (in case yours are lost or too corroded to reuse)
- Second, I read a number of reviews where buyers expressed frustration with the screw holes in the mounting plate not aligning with the original holes in the oven.  I did not have this problem.  The holes aligned perfectly, so either the manufacturer corrected their mounting template, or their replacement part is identical to the original.
- Third, the electrical connections are not the slide-in type, but are the much more safe and secure screw-in type.  Installation is trickier, but I was able to remove the old broiler element and install the replacement within 30 minutes.  This included locating the right size tool to remove the 2 nuts holding up the ceiling mount, element mount, and electrical connections. (TIP: Before disconnecting the electrical contacts, wrap a long twisty-tie to each wire so that they do not slip back into the range.  If this happens, you'll need to remove the rear panel of your range and push the wires back through the opening and into the oven so they can be attached. There are several DIY YouTube videos showing you step-by-step procedures for replacing your broiler element. Oh, and turn off the electrical breaker before doing any work on your range.)

While this replacement broiler element says that it will replace model WB44X173 and WB44X185 broiler elements, I can tell you that it's a perfect replacement for the model WB44X0185 part recommended to me by GE Customer Support (not sure why there's that added zero) and that the holes in the mounting plate align perfectly with those in my GE range.
