if you want the same material that is already there. home depot and lowes sells those same shelves in certain lengths and they have the holders that fit the original holes that are already there. only thing is you would have to cut the shelves to fit. i used some for a glass cabinet and they worked out great.
have you tried m&m hobbies and g&g railroad. they have a nice selection of models and supplies. m&m is on the east side and g&g is near medical center on times bvld.
didnt know if its been talked about before but i thought it was pretty cool resin kit. i ran accross it on ebay.
