get hard to find one for the Buicks.  Most are listed for both na and turbo cars...origina
 lly, the turbo was a bit heavier.  Not sure if the balance was different or not given that the turbo cars had heavier pistons.  Most say not.
Pioneer lists a separate number for the turbo cars and that is what Webber sells.  Twenty cheaper on Amazon.
Mike is out of the CAT sfi rated oriental specials.
Someone selling a so called sfi unit on ebay for 40$....hmmmmmmmmm
gonna go the Pioneer route, I think.  Kinda hate to go used in case I get one that has been abused like mine 

On another note, I just noticed my Hotchkis bars for the challenger are for an A body and not an E body Challenger...L
 OL   so goes the car life.
