in the past i had some offy breathers - that i set on - traced with a felt pen where they where going to be put - then drilled several small 1/4 inch holes in the inside diamiter of the breather , then drilled the appropriate holes to fasten it - threw bolted making sure there is no interference with rocker /threw bolts - then after - bolted on a nylock , cut off excess - and flattend off the end of the tread and epoxied the bolt/nut for saftey
Do you have a link to the ebay auctions? I'd like to check these out! Thanks
