Hi All, as well! All 300 lettercars were assembled at the Jefferson Avenue Assembly Plant in the eastern Detroit. Jim, you are lucky to have such a golf partner. Perhaps he would be interested in relating some of his "300 experiences". Having worked in Resident Engineering at several assembly plants (including Jeff in later years) I can imagine that the 60-62 300s, were a pain in that "special" place. Since almost all cars took the same seat brackets, these would have been included in the floor subassemblies as received from the stamping plant. At least that is the way I remember it. The last thing either the stamping plant or the assembly plant needed was another part number to deal with. The volume on the 300s was so small, I am sure it was much more efficient to simply torch the bench seat brackets off and wire weld the four bucket seat brackets on in the revised locations. 300ly, Gil Cunningham In Cold Tallahassee, FL In a message dated 12/8/2010 10:57:15 A.M.

He's been all around and through my survivor H. He told me that it would come down the line like the sport 300 or Newport. At the time of installing the interior, they would pull them off the line onto the 'letter' line. He has checked over my H and confirmed/admitted that the weld joint you see in the trunk/taillight area is perfect! "They did an awful job, but yours is a perfect example". (I think it looks like Hell) He also said the letter cars were a pain-in-the-@** to build, one factor as to their high price. So as to those brackets, I haven't pulled my seats out, but by going by what the ex-plant manager told me, YES, I'd agree that they are supposed to be there. When those brackets were installed, they didn't know that car was going to be a letter car. Just my $.02.

At first too I thought someone had done a pretty crude job changing the rear seat attachment brackets. Then I assumed that with the few H interiors that were put together it probably was cheaper to just modify the normal bench seat attachments.

I panicked! Did I have a clone? After rechecking all the numbers, I confirmed that the body is correct. The original brackets were for a bench rear seat. I am assuming that all 2 door hardtops came down the assembly line set up for rear bench seats and that H interiors then had the brackets changed to accommodate bucket seats. Can anyone confirm this? Underneath the carpet pad, I found a 3"x 6" red color plate with a paper tag: 1962 "S" Series C-8580-ES Imperial - Chrysler E23N043 - B - 154026 Caramel Enamel PART NO. 2178166 May 10, 1961 from the COLOR STUDIOS of RINSHED-MASON Company Also found a Wrigley Spearmint gum wrapper, headliner trimmings and an assortment of fasteners.
