@Cougar I'll be damned. I'd swear I took these measurements at some point and I got it into my head that we were at 4" depth these days, but I'm clearly wrong.
My 2006 F-512 measures slightly over 4-1/2". My 2007 F-412 measures almost exactly 4-3/4". See pix below, respectively.
Cougs, can you remeasure your Tacoma F-412? I suspect your F-412 is 4-3/4", not 5". But clearly you were right; this is definitely not 4"!!!
I
think this is narrower than the mid-90s JF-30-12 I used to have, which I
think was 5", but I'm not at all sure.
