Okay I?ve read here that members have ?62s with the 3 horn set-up. So I looked on my ?62 LeBaron and only 2 horns are on there with no signs of there ever having been a 3rd or trumpet horn. No bracket for it, no extra wire for it. So I go to my ?62 Parts Catalog which most would agree is pretty much the bible to go by for anything on your Imperial. They only list a left and a right horn set up with no mention of a third horn. Also there is no mention of a 3rd horn (or any horn for that matter) in any of the sales literature I have and I think I have it all expect the Dealer order book. However the Parts catalog almost reads like there were two different horns for the Imperial like maybe one set for Crown and one for LeBaron? Just guessing. So if you experts can tell me from what is printed in this parts catalog what is going on with horn selection on the Imperials for 1962 it would be most appreciated. Here is what is in the catalog:Page 8-35 section 8-32-0 HORN:Right Auto-Lite, SD3, SC1, SC2 No. 2291 424Left Auto-Lite , SD3, SC1,SC2 No. 2291 423Right w/Mounting BRACKET, Sparton, SC3,SY1 No. 2291 420Left w/Mounting BRACKET, Sparton, SC3, SY1 No. 2291 419Is Auto-Lite and Sparton brand names for horns? Why would they list both for Imperial?I guess what I am getting at is if your Imperial has a 3rd trumpet horn set up was it a dealer add-on and not a factory option?.
