Even with the seatbelts in the guides mounted to the headrests I had trouble reaching them. I fabed up some 1/8in x 1in wide x 3in long flatbar to offset the guide further forward. 1/2in holes in each end of the flatbar. One end for the headrest post, the other hole with a bolt and nylock for the guide bracket. Being further forward allows me to reach the seatbelt. Some black paint and less than $10 in parts for both sides.
