Printed a set of my adjustable body mounting posts and after trimming to just under length I have epoxy glued them in place. Once the glue was set I then fitted the adjustable caps and screwed the chassis in to get the correct length and after fixing in place with super glue I then after removing the chassis set them with more epoxy glue. Have already trimmed the rear of the chassis I found that this had not been necessary as I had to trim the rear body valance anyway to clear the mounting post caps.
