I was able to check one out. Completely different MAF sensor. So I was able to get mine to seal by screwing the two halves together with wood screws, which work better in plastic than sheetmetal screws. Only problem is that the entire assembly needs to come out in order to get to the filter. Oh well.
I'm in the process of getting my $400 '97 up and running as a daily driver. The air cleaner box is damaged and doesn't look like it'll provide an adequate seal with the filter gasket. Looking on eBay, EVERY SINGLE air cleaner for sale is for models '98-'02. What gives? Is there really any difference between cleaners for '97 and '98?
