77 thru 79 chevy swb frame

i am new on here just wondering if anyone has any pics of their frame on a 77 chevy swb 1/2 ton truck. i bought a 77 model that has been wrecked and the frame looks bent on the drivers side to me but i am no expert on this, the truck was in bad shape but the bed was good and it has a 305 that runs with a 350 turbo trans,i have bought a 79 longbed that was a stolen recovery but was stripped the cab and doghouse were good on this truck so i am going to put them on the 77 frame but i got to looking at the 79 and the frame looks like it is bent in the same place as the 77 but the 79 was not wrecked,the 77 was hit in the front and right side.the place i am talking about is where the frame comes out from under the cab and looks like it hugs the manifold on the right side.i was checking to see if anyone had pics of this so i could compare,before i have it sent to a body shop to be pulled. thanks joe
