Strut question

Ok so I guess we need some history? I drove a 1986 2wd Hi Lux for four years then from Delaware to the Oregon Coast. I lost the windshield, exhaust, brakes, clutch, and two tires in transit. Hindsight says i shoulda fixed it, but I digress. I replaced it with a 2011 Access Cab 4WD SR5 which felt like driving a Suburban. When finances allowed i traded to my present rig, the 2014 base 4X4 in question. ...there is nothing TRD on my rig. I purchases 4 yellow + blue Bilsteins with the coils (no hats) from a 2014 TRD rig off CL. Will they fit my rig and if not, why? Ive heard TRD used different uca's but there cannot be that much of a difference in our suspensions, can there?!? THANK YOU!!
Was at Schwabs today and the tech said they (TRD Bilsteins) were too long so I called the dealer i bought from and the parts dept guy said they "should" fit...
