I received a Big Sucker air cleaner for my 04 Sporty, but the eBay seller didn't have instructions inside. Can anyone help out with install? There are four large bolts ... I'm guessing that they go into the engine ... but there are only two large washers. Is that right, and if so, on which bolts do they go on? There are two gaskets and one spacer. There was one sheet in the box -- a change in installation for 07 and later -- that explained the 07 and laters need the spacer. Do I not need the spacer for '04? Just one gasket? Where do these o-rings go? and there's a small tube of something ... loctite? lube? There's some smaller washers, too. Needless to say, this is a little frustrating and it's not the first problem that I've had with this seller.
