Hi all, My earlier,March, 300C has this plate too, my later production,April, 300C does not. I would hesitate a guess that it is an early versus late production thing........Wayne? I know of only two hardtop race cars built with the convert X member frame and fully box welded rather than stitched , both Kiekhaefer Special Order cars. One existing. It is important to question all unusual features and the possibility they MAY have been factory special install, but the fact is, most left the production line as a standard build and most modifications were done by various owners through the years. Let's not build cars into something they are not. After all, all 300's are special. 2c worth?

Christopher - What you are describing is what they used for the body mount under the trunk floors of convertibles. I'll bet that you also have an X-piece on your frame. It's all about extra strength and rigidity. On my 59 Dodge convertible, I discovered these welded to what was left of the trunk floor. When I welded in the new floor, I made sure that these were included. BTW, I believe mine had bolts running thru them, anchoring the trunk floor to the body mounts.

Otherwise every factory weld still as good as new, although welder guys cannot believe how rough/crude they look. > > Christopher Australia, burning some dollar a litre gas in my driver 300C today > _________________________________________________________________ > Messenger's gift to you!
