is it Vq or VG your talking bout if VG mazworx.com is the place to go to. they can machine the housing to fit in the s-chassis not sure if they do just for vg swaps but it might be an option and they have a custom drive shaft to fit the z32tranny to the s-chassis thats what i plan doing is takeing the z32 tranny and hookin it up to the sr stronger gears
good luck wit the swap
