I am thinking about adding hoses to the front and rear of several diesels in my Nscale lineup. I'm wondering, since many of the manufacturers model the hoses right into the front plow area, when you add some aftermarket hoses like those from BLMA, do you sand away or otherwise remove the existing hoses? The work area seems pretty small to sand down, but do-able with a steady hand. I'd like to add grab irons too and wondered just how hard it is to add them to Nscale diesels. Do you simply glue them on or drill into the body for a more proper mounting? Any info on "how-to's" in this area of modifications would be appreciated. I'd like to add them for more realism and better pictures - but I've never seen it done in Nscale (by that I mean actually seeing it first hand) - so I'm wondering just how hard it is?
