I'm going to do a write up on this later but I thought some people might be interested to see the progress Well first we need to gut the back of the rex. inventory the hardware and test fit lets find out were to mount our seat. seatbelts, and seat hardware, exploration this is were to mount the lap belt bolts. this is were the rear upper seat back latch mounts to, right below the speaker the black circles will be removed to expose the lower seat mount clip locations checking were I'll need to either weld or bolt the upper seat bak pivot some mods will need to be done to the trim, but hinda was nice enough to mark the locations this little black circle plug on the passenger side is actually provide for a child seat teather attachment quick test fit to see how everything going to look and figure out were to mount the belt buckles As you can see almost all mount points and harware is already present in the USDM model CRX which makes this install actually a lot easier than I thought it was going to be. I need to weld in to nuts for the belt buckles and possibly weld in the pivots for the folding rear seat. it looks as tho they were rivited in before anyway I'll most likely be doing that work this weekend. I'll update with more pics when I get to that point. ------ Hardware update, the bolts for the seat belt buckle and lap belt are 7/16-20x1in. , the bolts for the seat latch brackets and the pivot bracket are M6-1.0mm x 12mm also you'll need two 7/16-20 nuts to weld to the frame to be able to mount the buckle.
