Ed, I'm trying not to get too overzealous with the "rock hoppers" simply because the tooling is so crude and I figure we'll eventually get some nice Greenville cars. First, I stripped them using "Purple Power" but be careful that stuff is wicked. Then, I just filed off the peaks, ground down the internal "brace" on the inside of the ends so that the inside of the end would be flush. (if not about 18 scale inches thick!) I also filed down the stirrups, only because some were already broken and it is easily within my skills to drill a few holes and add the BLMA versions. (which may trick the eye into thinking these look a little better...maybe?) I will also replace the brakewheel with something better....maybe MTL since I already have a couple of them laying around. Outside of that, painting/decalling, and adding trucks/couplers with 36" FVM wheels, that's really all I got.
I figure I'll post a pic once I get one ready for primer and see if anyone has any "quick and dirty" suggestions. (outside of putting them out of their misery with a sledgehammer)
