Frog Jumper 3662 Posted May 22, 2016 FS: Thorp Dirt Burners #4583 and #4584 - Fox Pressure Discs RH and LH. Vintage parts. New in package. Absolutely no rust. These are as clean as they get for being 30 years old... I got these as part of a larger collection of Thorp parts. I don't have a Fox, so I don't need them... $15 gets you both. Includes shipping in US. If you are overseas, we'll work out some arrangement for postage... http://jpegbay.com/gallery/005267690-.html#1 Terry Share this post Link to post
