banks turbo boost pipe

[gphudgins]

I have runa Banks sidewinder turbo in my '83 6.2 motorhome for 15 years now. My last engine I have gone to is a 6.5 with serpentine belt system. However the boost pipe from the air box to the air chamber does not fit with the A/C compressor and alternator swapingt sides as the single belt system does. A later model pipe is available for '88-'93. Does anyone know when the serpentine (single) belt system was used?

'88 up in the new bodystyle stuff, but I'm not sure that the exhasut manifold didn't change.
