Full install how to guide for the deuce double hoop roll bar from hard dog.
Hard dog roll bar miata install.
Fig 1 once the hard bar and seat belt reels are in position start but do not completely tighten the footplate using the mounting bolts from the hardware kit and the original equipment small od flat washers from.

I m doing this on a 1994 na miata which will be exatly the same for any 1990 19.
This is a little tedious cause you cannot get a socket in there and you ll have to use a combination open end and box end.
Using the 17mm bolts that held the bottom of the seat belt mechanism in place secure the bar to the seat belt tower.
The roll bar foot plates fit against the seat belt reels which stay in their original location but do not use the original spacers.
