Convertible Car Seat for 2010 Access Cab

Hello! I am in desperate need of your help. I have been reading threads about car seats for a Tacoma access cab truck (2010) and have found that it is possible but no idea what brand/model car seat (not infant) will fit in the back jump seats. I tried calling our highway patrol and car dealerships and no one has answers for me either. I went to Babies R Us and Buy buy Baby stores to try them out in the truck, but none fit. The jump seat sits at a 90 degree angle and the fold down head rest puts any car seat at an angle. This is not our primary car, but would like to put a seat in this one in case something goes wrong with our other car. I apologize, we tried so many car seats out and I cannot remember all of the names. The ones I remember are: evenflo triumph, Diono radian rxt, Graco 65, peg primo, safety first hybrid, Chicco nextfit, and recaro performance. My son is 14 months, 25 lbs, and 33 inches tall. Any suggestions? Thanks in advance for your help.
