How much does a TF weigh? (suspension purposes)

[hotrodrookie]

I don’t have the scales (let alone a complete truck to weigh) but I have a 59 swb step side. I’m trying to figure how much of a rear coil over spring rate to invest in.(building a 4 link) Right now I have 200lb rated springs, any of you guys know what the weight would be of the truck? Rear of the truck?

Anybody have any input on spring ratings and how they make the truck feel? I’m new to this and this is my first time building a suspension.

Thanks
