Hi Guys

Reading GM documents about replacing the frame rail on a C6 there are 3 placed that you can splice the new one in. Looking for suggestions as to which place is the best.

Front most on will not work for me..

The second on is in the middle of the bend from the engine compartment to below the passenger compartment

Third is in the middle of the door sill (Behind the rocker panel)

There engineer in me says the "best" place would be the middle of the door sill. that section has the least amount of stress on the frame. The only problem is in order to get the frame rail out there are at least 3 other connecting point to cross members and windshield that would need to be removed and the more that is removed the more that need to be re-welded and more possible problems.

I am leaning toward splicing it in the second section (the bend from the engine compartment under the cab) but just looking for some insight form others

Thanks
Mike
