Tourch time..

[swamp rat]

I'm a good hand at using a torch but this is the first time i need to use one for removing the rear leaf springs on my truck, the bolts are froze solid in the sleeves and cant bang them out even tho i got the nuts removed. I know the rubber is going to catch fire if i torch the springs, The bed is on the truck too.

Not sure how bad the flames will get???

Any advice appreciated.
