That's it! Same color interior. Although mine is quite faded and there is a debate as to whether the greenish tint is mold or it's just faded or ??? Pics to follow in the relatively near future. Thanks so much JamesDean for the advice. I looked at the entire 300SD rust repair thread and am emboldened to do the floor pans in my 300D. I have access to an old stick welder, but I may cough up the chump change for a new flux welder from Harbor Freight to have experience with that as well. Some students from the local technical high school who are doing much of the welding as they are certified and have experience, at least classroom experience. This will be an opportunity for them to get 'real world' experience before they actually get their first welding jobs. Cheers!
