Yes dan that is exactly what early chassis owners should have done but it is 10 hours labour as its engine out.
That's still a lot less labor and parts than replacing the entire chassis.
I would think that MMC would take the bull by the horns and setup a team to do nothing but strength the chassis' of the older M3W's. This would ultimately save them 100's of thousands of dollars and customer loyalty.
My guess is that even a cracked upper frame rail could be repaired with confidence and then strengthened and reutilized rather than a complete new chassis.
With the right engineering, I think that's an oxymoron, the reinforcement parts would all be made up in advance and be nothing more than a weld in fix and then respray the frontend with urethane paint; not as durable as powder coating, but more than effective for a repair.
You just know that this is only the tip of the iceberg for cracked or broken chassis'.
