TC:
Would love to help, but I mounted dual Rebat aircraft batteries as original, and they use a tray that is somewhat larger than the tray Kirkham furnishes. I still have the Kirkham chrome unit stuck away in my parts bin.
Lew:
The cars come with aluminum sill strips. They are unfinished, and require polishing or brushing before final fit. If yours includes the interior already installed, I would imagine they will be already mounted. Either way, you may want to refinish them. The AC parts came with logo, the Kirkhams are plain.
