what is breaking point??

[mothertrucker424]

what kind of off road abuse or playing can a stock '72 handle?? what are the weak points and positive points of this year??

this is my daily driver and my weekend light duty mud truck

i dont wanna push it to breaking and wanna bring it back to a nice looking truck
not really show but something to be proud of . i will be lifting it soon 4-6" with 33"s i have gathered many of good info so far but i figured i'd get an answer on the breaking point??

thanks
