quick question, attaching body to cc-01 chassis

[tjvan]

quick question, seems obvious, but curious to know the best way to attach a body to chassis, done with modification of land rover defender body, now will need to mount to cc-01 chassis, which has had the wheelbase modified to fit. I figure velcro can be used for the actual attachment, but what is commonly used to construct the posts or areas to actually mount the body?? thanks
