The SR has these 12-point short-head bolts on the flywheel. I don’t plan to use them again and I know they can be replaced with a 6-point tall-head bolt from another Nissan vehicle. I’m just not sure which vehicle. I can’t remember if its Altima or Maxima or what year. Anyone? 12-point head bolt from SR20DET, and the mystrey bolt. ![http://www.son240sx.ca/images/gonad/oct10/flybolts.jpg](http://www.son240sx.ca/images/gonad/oct10/flybolts.jpg)[/img] ---

This shouldnt be a mystery !! measure the length and pitch of the existing bolts and buy new ones !! they dont need to be from another car, they can be from Canadian tire. oh yes they’re most likely metric, find a nut that fits the ones you took of the flywheel and take that nut to the store in search for new bolts. ---

You don’t say? :roll: It would take me like 2 sec to call up Nissan and place an order for these bols from a Nissan vehicle then to go to CT to not only not find mathing bolts but then have to go to other specialty shops just to find metric items. ---

CT bolts are certainly not usable in that application… metals have different strengths and the CT bolts are SHIT in comparision… i wouldnt trust those to build a shed . GT ---

Yea, he sent me the pic (along with the clutch he got) but forgot what car it came off. So I made this post. He later foudn out its from a **1989 Nissan Maxima 5-spd** but I guess it’s always good to get a second opinion. :dunno: ---

take the bolts to brafasco or spanar. they will get what you need. and like doba said, it should be quite simple to figure out the bolts you need by measuring threads and pitch. you’ll probably want a grade 10 bolt to be safe. ---

The flywheel bolts arent a high torque bolts. Ed, I hope you are 100% sure about them being 1989 Maxima 5-spd bolts because I wlil be ordering them tomorrow. :squint: ---

And the only reason I’m saying they are from that car is because that’s what I found in my msg history 6+ months ago. ---

DO NOT use CT bolts or the like for your flywheel. They won’t be the right strength and probably won’t have the little notches on the back of the head to dig into the flywheel a bit to stop them from backing out. Get the bolts from Nissan. The 12 points are from a 300zx. Not sure about the 6 point ones. I just bought a 12 point socket for 3 dollars and used the 300zx bolts. ---

Nissan wants $8/bolt for the 12pt 300zx and $3.25/bolt for the 1989 Maxima. ---
