when doing the conversion i have seen a lot of people cut out just the tunnel and small parts of a sierra and fit them into the new shell but why do people bever just hack the whole floor pan out of a sierra then chop everything out of the new shell and basically just weld up around the bulk head and sills? would that not make it easier for alignment etc

maybe the floor would need a cut and shut in the middle but surely this would still be easier???

yes or no???

anyone got any pics of doing it this way or links to other builds?
