Turning a G-Scale 1:29 Bachmann 98908 Hopper into a Covered Hopper

First, I made the two top pieces: “Top Half A & Top Half B with 3-”Center Dowels" then glued them all together. I used “Glazing & Spot Putty” I bought from any auto parts store and hand spread it over the top but be careful not to get any putty in any of the indentions! I sanded it all down with 400 grit wet sandpaper and repeated as needed. Print 8-“Manhole Lids”, 4-"Walk Platform Sides" and 2-"Walk Platform Ends". After all the body work, glue on all the covered top pieces and glue to the Bachmann Hopper and paint to your desired color. I printed the “Brake Wheel Housing” and put it in between the frame uprights on one end and I used the brake wheel that came with the kit (the kit brake wheel was supposed to go to the top) and cut off the shaft and glued into the housing. I wanted body mount couplers instead of truck mounted so I made 2 each of “Coupler Mount Blocks and Coupler Body Mounts” and installed Kadee 906 couplers. The “Block Mount” fills in the gap in the frame where the third screw goes for the 906 couplers (you'll have to drill a hole or use a sheet metal screw)(the blue coupler part in the pictures was for picture taking only). I cut off the coupler mount tongues off of the two kit supplied trucks and screwed the trucks onto the frame.
