Don't have all the figures handy, but you can find the exact $ for each and every part Van's stocks on "The List."

Many of those items do not show up in the parts catalog, so you would have to ask Van's. Also, when Van's deletes a part for a kit, they only credit you 80% of the retail value of the part. I deleted the gear legs from my fuselage kit. I'll try to find the figures for that. The rest of the parts are in the finish kit and I haven't ordered that yet but I plan on deleting most of those parts as well. If you delete a lot of parts, it might be more cost effective to order the parts individually rather than delete them from the kit.
