Blazer frame questions

[Chevy_mud_truck]

Ive got a 89 k5 with a bent frame I've been doing some research and I keep getting that they were bad to bend at any kind of abuse or off road use ive looked at a few replacements couple was bent also one was really rusty one a guy was asking to much ive got a suburban frame from a late 80s 3/4 any one ever cut a suburban frame to fit a blazer body on or should I keep looking for a blazer frame and reinforce it to make it survive the abuse of off road
