My 41 Chevy frame has some rust through on the K-member. I have looked at a lot of ways to fix this, and just when I think I have made up my mind, I see it done another way and begin to wonder. So, I thought I would check to see what you think. I was going to replace the k-member with 2x3 .120 wall and add struts of the same going back to just in front of the front spring mounts on the rear. Making the crossmember solid forces me to pull the engine in order to get the automatic transmission out if I should ever need to. But I am afraid that splitting it with a bolt in transmission mount will negate the rigidity. If you have any experience, photos would be appreciated of what you have done.
