Sorry Bob, I wasn't clear. The Finescale 360 frame does accommodate the RC coupler assembly properly. My coupler height comment was because I seem to have at least 2 heights of P&D (OCS) brass truck bolster on hand and I'm not sure which one is really right for the GP9. I do have some P&D F Unit brass trucks which I may have transposed. Needless to say, if I use the wrong one I get incorrect frame and coupler height.
I recall seeing a picture online of 3 (may have been 2) P&D brass truck bolsters of different heights. I thought it was on A&O or smugmug but perhaps it was from Jay C or someone else. Sorry for any confusion.
And my joke about lifting by the hood was because the body can come unglued from the floor due to the extra weight connected to the floor by the tangs on the motor mount, which work great as you say. But my glue joint from the plastic floor to the plastic hood came undone when I first tried to pick the more heavily weighted loco up by the hood. Lesson learned!
Again, sorry for any confusion. I was hoping to help anyone doing these conversions to avoid some of the (many) mistakes I've made along the way. That might be better achieved if I didn't talk in riddles...
