Coming apart was easy. Locally the appliance supply wanted $68.72 + tax, received it next day from U Guys at a fraction of the cost.
Now installing it was not so easy, attaching the wires proved to be quite a task. The old element had sheet metal screws in & out easy, this unit had tiny machine screws. To try an hold the two wires together and set the screw was quite frustrating. Atlast I used a awl to align the wires and used a small magnetic screw driver.
I'm sure if I had removed the oven door access would have been much easier, but I wasn't going that route.
