Club Member and fellow engineer Terry Hoemann checked out his spares and several parts catalog and has solved the riddle, as explained below. The errors appear in both the 55-56 section and the 57-58 section of the parts catalog printed 11/28/58. The proper door window regulator handle (longer handles-about 3.5" center-to-center) part numbers are 1602528 for 2dr & 4dr 1955-58 Chryslers & Imperials. The quarter window regulator handles are shorter in coupes and convertibles and carry part number 1602529. The current e-Bay auction lists a pair of NOS 1602528 at: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8024771995&ru=http%3A%2F%2Fmotors.search.ebay.com%3A80%2F%3Ffrom%3DR40%26satitle%3D8024771995%26fvi%3D1 Or, plug this into the e-Bay search window : 8024771995 The required opening bid of $29.99 seems reasonable. Thanks to Terry for clearing up one more mystery. Can anyone inform me as to whether the riveted knob would have to be ground off and somehow replaced in order to rechrome these handles? Looking at a spare, it appears there is a little Belleville disc spring under the rivet head on the backside. Or is the apparent rivet head actually the head of a friction drive pin set into the knob with an interference or shrink fit? Merry Christmas from Brentwood, CA (60 and cloudy at 4PM) Rich Barber From: Terry Hoemann Look under group 23 14 79. The shorter handle is part no 1602529 while the more common one is 1602528 for the front doors under group 23 14 18. This is from the original 55 parts manual. The later one (55-58) has an error it appears. Those numbers agree with the spare handles I have in stock. Terry Hoemann ------------------------ Yahoo!
