How much weight gain from adding a Dana and roll cage.

Mine I took a picture of on the scale after making a pass and posted it on here. Not all that long ago( this past summer). And anybody who has seen it knows it has no glass and no stripped down interior. And knows the size of me ..lol
I am a hater of people who say there car is heavier to make it sound faster.
I'm going to say what weighs when I figure it out.
How much did your 69 weigh. I think those cars are heavier than a 70 to start off. But I know I'm adding extra weight and won't have any glass parts off the bat & will be adding in additional bars because I'll probably end up replacing my floor. So more framing too.
