I've already tried searching through the forums but they either didn't answer or the links didn't work, so here i am. I'm missing the hardware to put on the main pulley and rad fan and cant find any information on what size and thread pitch they are but I've been pondering the thought on running dual pulleys since i deleted ac and air pump. I was wondering if there is a preferred kit that everyone runs and if it comes with hardware need to put them on since i don't want to put the money and still be in the same predicament or if anyone knows where i can get the bolts or what the specs for the bolts i need are. im sirry if the dual pulley question is a dead horse being beaten alive but thank you to anyone who can help. i have a 1986 rx7 gxl n/a.

 

Water pump/fan pulley bolt sizes
For pulley
Use 4x M6x1.0 thread 10mm length flange bolts

For fan on top of pulley
4x M6x1.0 thread studs, approx 1.5" long
4x M6x1.0 flange nuts

You can buy bulk fasteners at belmetric.com.
The flange bolts and nuts are all over your car so you can order a bunch to have on hand

 

thank you so much!!
