subframe question

[TRKK11]

I also have been thinking about another thing. The subframes on the newer w-body cars are made of aluminum. i had an 06 impala up on my lift, and was looking at it, and it appears that they are the same as the heavy steel subframe on my 90 lumina except for the one side of each control arm. Does anyone know if they are in fact the same dimensions, and if i could get my hands on one, just have the control arm brackets welded on. Doesnt necessarily have to be the 06 subframe, but any of the aluminum ones.

Very interesting. I'm sure a salvage yard somewhere has one, take some bux though.

I can say that they are not bolt on they will not match up.
