How to make a stand for your 1/12 scale Agora/Hachette Routemaster model

How I am making a stand for the 1/12 scale model Routemaster by Agora/Hachette, basically I have drilled the framework on the flat pads that are underneath the chassis with a 6mm drill and then I filed the holes to get rid of any metal burrs etc then using M6 coach bolts with double nuts and washers I will when I put the wheels on the chassis measure how high I need to get the model off the ground so that it takes the weight off the wheels then I will saw the bolts accurately to give a little adjustment and fit the nuts washers and bolts , if you are thinking of doing this mod then please bear in mind that the bolts cannot go higher than the chassis as the floor of the bus fits flush onto the chassis .
