Product review (5 stars): Cheap, but works like a charm
Purchased for my Estate dryer.  Fairly easy installation, you just have to remove all the screws holding the back dryer cover on.  Once that's done, you can easily disconnect the old heating element and thermostat and reconnect the new ones.

If you're already changing out the heating element, I would also recomment you also order the thermal fuse and thermostat for your dryer.  Will cost less than $10 dollars, but go ahead and get it out of the way...then you'll know it's new and won't have to open it back up later to replace those two parts.
