I'm peeved! Not that any of you should care. I now have 7 BLI locomotives. I consider myself a fairly good customer of theirs. I admit, I don't have three of each type. I would like verification of my decisions concerning application of coupler cut bars. There are no instructions enclosed with the locos, and this applies to my latest, an Intermountain Railway F7. Do the bars go underneath the MU hoses AND under the coupler head on BLI's E6? The front coupler is the one with the rounded front? It would need holes drilled in the pilot, to apply? (If so a drill mask would have been nice.) I have asked BLI twice. Failing an answer there, I asked Max Models. Whoever answered the email didn't read beyond the subject line, and proceeded to give me instructions for ordering these parts. Can anyone help?
