Does anyone have any videos or information on how to replace the rear framerails on a base model 1967 Camaro. I will be replacing the floorpan and trunk pan, and have seen the videos from SuperChevy (they make it look so easy), but I have not found anything on replacing the rear rails. I am curious if it is better to do part of the rail or the whole rail, the price is only $20 more for the whole rail.
