Hapijac does not make a system like you saw that fits our trucks. The only system they offer for Tacos (really any small truck) is the system Rangerdogg & I have. Torklift MAY have one, but it will be spendy, and may mean that you have to weld 2" receivers to either side of your frame or some such nonsense. Please investigate it for yourself though, and if you find a more elegant solution, I know I'd love to see it.
I did find one other mounting method a guy was selling on ebay that bolted through the front of the bed, and stuck out from between the cab and bed, but it looked like alot of work to put them on. I have been pretty happy with my tiedowns. Happier than I thought I'd be.
Most folks on here don't use external tiedowns at all, instead using a concealed system, but that can be a PITA if you mean to remove the camper alot. Much better for a dedicated camper and truck. External tiedowns will save you from a few busted knuckles!
One word of caution: you shouldn't get ahead of yourself, and install the front tiedowns before you have the camper. On mine, the front mounts on the camper are not even from side to side, so to get the best angle the front mounts are in slightly different places on my truck body. The rear mounts can only really go in one place, so you may be fine to mount them beforehand if you're so motivated.
Please 'pay it forward' if you're going to get your popup TC, and give us all updates and share knowledge by making a build thread. I love to read about other folks TC experience!
