1st gen housings are either a 21 cm or an 18.5 cm, depending on the year of truck. But yes, a 21 cm, 18.5 cm, or a 16cm bought from a vendor, will bolt right on.

Just make sure the center section is level and tight into the exhaust housing, or you will trash the turbine wheel.

A non wasted gated housing is shorter than the one you currently have. Your exhaust pipe will move forward 1 1/4". Make sure you have that much room for the pipe to move before you do the swap.

On a 1st gen we have to add the same amount for down pipe to clear the exhaust manifold with a wastegated housing. The 2nd gen used the same exhaust manifold. But I am not sure of the differences in the downpipe.
