Does anybody know where I can find repo or a very good set of door sills for my 66 Vista cruiser, I have tried several companies the most recent one listed them as a fit from 64 thru 67,... they arrived and do not fit they are 39 inches long I need 27 1/2. They told me they misspoke and apparently do not have them.

 

Looks like they sent you 2 door door sill plates. All the new sets show 68-72. I have the set in the link below from Fusick in my Vista. They measure 27-1/2" in the front and 23-1/2" in the rear. They might work for your car. Looks like the main difference is the orientation of the ribs. 64-67 runs perpendicular to the jam. 68-72 runs parallel to the jam. The image in the eBay add shows 64-67 style ribs, but the ones pictured below are what you will likely recieve.

Those are full size wagon (B-body). Notice how they roll around the lower door jamb. Also, the rear doors on a vista are longer than a regular wagon or 4-door.
