I need the bracket that holds the MAP sensor on an 87 GM 454. It may be the same for 350 engines and for the Blazers, Burbs and old body style 1 tons up to 91 ... but I'm not sure. If it looks like the pics. I'll take it. I think there are some double ended manifold bolts this fastens to, if you have those and any other mounting hardware, all the better. $20 plus shipping to San Francisco. http://blog.mannon.com/archives/cat_wanted.html Thanks, Eric M.
