I hope this is the correct forum;
My 85 monte has a stress crack at the top of each b-pillar, starting right at the corner of the door window and going up and back about 3/8" to 1/2"?
After i fix the crack itself, what should i do to make sure it doesn't return?

Since it's an 80s Monte Carlo, I would be checking the rear frame to see if its rusted out...............common problem on GMs of those models...Monte Carlo, Cutlass, Regal, Lemans, etc

I don't know how much help this will be, but I had a similar problem I encountered this weekend. The doors on my 68 vert had two small stress cracks in the metal, so I thought I could just braize some steel into them, but I was wrong!!! I burned a hole in both spots, which I had to fill! I think a wire feed welder is best to use for this application. Once they are welded you shouldn't run into anymore problems unless there is a structural problem somewhere. Mine occured originally due to poor support which I fixed. Maybe someone has some better ideas, I would like to hear them so I don't make the same mistake twice....

The car's frame is solid, the floors are solid. It's only a stock 305 and some kumhos.
If this wasn't a street car, believe me, a roll cage would already be in there.

just a thought, could it be lead filler that you're seeing crak?
that sounds like about the area where they put the roof on.

When you grind into it you will find lead over a brazed joint, which is not strong to start with, and the brass and the lead interact to make an even weaker joint.

I've had good luck re welding the joint with a mig, then using bondo. The lead has no flexibility, while the bondo does.
