The funny thing about the F is that was the year they produced the most 150s, yet interior parts are the hardest to find for that model. Good luck if you have to replace your interior panels behind the seats!
The market for 150F interior plastic is largely limited only to 150F's, a relatively small number compared to all 150's built. It's a guaranteed "niche" market that a small startup supplier should explore (Bengie?)! The "universal" fit of all later models combined means one part number fits a larger total number of 150's, regardless of specific model, attracting the larger suppliers into production.
