Spectrum N 4-8-2 Decoder Installation

[rlandry6]

Has anyone installed a decoder in a Spectrum N Scale 4-8-2? I'm wondering how the degree of difficulty during disassembly and reassembly compares to the N scale Spectrun 2-8-0 Connie. I just finished one of those and I'm trying to decide if I want to tackle the Lt Mountain.
I sent my Kato Mike to Fred @ Loy's Toys for the decoder install. I didn't even want to do that one. The Connie is my first steam installation, and my confidence is a little better than it was.
I'm wondering if the LT Mountain is assembled similar to the Connie..
