I bought this from a HAMBer about a year ago and realized it will look too small on my Chevy 6 valve cover. It is however, a great looking and rare breather with two (siamese) mounting stands. I believe its an Eelco and have seen another on ebay in recent months. It mounts flat, not angled and has 2 foam elements to prevent oil seepage. Dimensions are: Top 4-1/2” x 1-1/4” Height from mounting surface: 1-1/4” Stands: 1-3/4” x 11/16” Mounting holes center to center (on each stand) 1-5/16” Will ship worldwide. Now that USPS Priority Mail has increased their rates, shipping price will be based on your zip code, which will hopefully work out to less than Priority Mail. PM with any questions.
