If your state requires emissions testing better forget it. It won't be a direct fit, some mods will have to be made to the mounts, and then there is the tranny, the 90 won't work with that engine, the fuel system will have to be modified for low pressure, not high, then you will need to modify the driveline to match whatever tranny you put in. Lot of work and expense putting non emissions componets into a full emissions vehicle.
