2nd gen versus third gen alignment cam bolt torque and size

Just checking here but I've been having a click noise over speed bumps on my front lower control arms on my 2014 Tacoma. The sway bar has been disconnected and is in my backyard, SPC upper control arms that are brand new now and all new shock stuff. The second gen Tacoma cam bolts are a 12 mm and I believe the third gen's are also 12 mm. The third gen torque spec is 135/139 foot pounds and the second gen spec is 100 foot pounds. Anyone know the reason they changed? They look like very similar bolts, but they aren't the same part number. I understand there are host of things that make noise in the front end of these trucks but I'm really just interested in anyone that might have some info on the lower control arm cam bolts, thanks.
