Due to a high amount of Wisconsin ignition items ordered in error please read the entire item description before ordering parts.  Wisconsin used several ignition systems such as Per-Lux (Pertronix), Prestolite and Colt (Fairbanks Morse) on each of these models and one size does not fit all!  You need to identify your distributor before ordering parts.  This is a brand new dust shield for a Wisconsin VG4D, VH4D, W4-1770 or V465 engine using a Colt distributor.   The Colt distributor can be identified by the white plastic distributor cap held on by 2 screws and the points that have a wire attached to them.  The rotor is also different in that it is round on the side away from the contact.  If this is not your distributor design I do have 2 other listings that you can check out that have the Pertronix Per-Lux electronic distributor tune up kit or the Prestolite points distributor tune up kit.  I am an engine rebuilder that is familiar with these engines.  If you have questions on this item or need help finding the correct parts, please email me with your engine model, spec, and serial number and distributor number.  Due to the many variations of Wisconsin engines, if you do not have these numbers I can't help you.   Please contact me with any questions.  Items shipped to Ohio addresses are subject to sales tax.
