Has anyone modfied their 73-87 chevy to use kid car seats that use the car seat latch system. We have two britix carseats that we use in our 2006 ram with the latch system. Im going to need to being hauling my two young kids in my 85 k10 with non locking seat beats. Currently i can only put one carseat in using the center belt. Havent had any luck with getting a seat secure with the shoulder belt. I havent found any information on using carseat in older vehicles. So i was thinking of getting some of the latch system mounts from the junk yard. Hope this makes since, first time ive posted from my phone and still getting use to it.
