The only difference I've seen from the old style (1991) and the newer style (1992-1994) is the 1991 is a 3 piece set while the 1992-1994 is a single tube.
I'm actually running one from a 1991 since my old one (1992) got friendly with the alternator... and lost..
Anyway.. I think the parts explorer at the neighbors (a 1994) still has the intake tube.
If you cant find it on, let me know and I can check the ends of the tube for you to make sure they are good. My guess is shipping will be more than what he will want for the tube.
