Sweet glad there are more B11 sentras around, as for suspension either gotta adapt some full coilovers, or make your own as I did: http://www.nissanforums.com/b11-b12-kn13-82-90-chassis/176042-how-make-your-82-86-b11.html
The higher trim first gen sentras had tachs installed, just gotta find em in the junk yard xD. Kinda digging the older model headlight vs my later rectangles haha, I might have to convert in some time.
