78 Frame on 70 body (pic request)

[Flick]

First and foremost I want to appolagize if this has been covered. With my current location the sites search freezes up, so when I search for things I have to log out go all the way to google and try my luck..

Like my title says I have a 70 K10 on a 78 frame or so the PO stated. It has some pretty rough looking cattle guard bumpers on it and I would like to put back on the front and rear stock bumpers. Can anyone provide me a detailed picture of how the brakcet connects to the frame and what the backside of the stock bumpers look like. I do not want to purchase both sets of bumpers if I am going to have serious issues trying to get them mounted on the 78 frame. Thank you in advance.
