Took advantage of some wonderful weather to go on a salvage yard safari for my 115 chassis '76 240D. (Truly a spiritual experience, a sunny day and acres of vintage iron...)

I found a pristine hood on a 300D, even the correct color. Snatched it up before I thought about whether it might be a different size than my 240. Anyone know if they're interchangeable, or do I now have a beige snow-saucer in the garage?
