Vg30i/e MT flywheel bolt grade strength AT to MT swap

[RCWD21]

I'm searching for the bolts to hold the flywheel to the crank on my 87 pathfinder. I've got almost everything ready to go except the harness and these 6 bolts... I know they're 8x1.00 thread and if I remember correctly they're 20mm thread length.

 

I'm swapping from an auto to a manual transmission.

 

My big issue is the grade of the bolts. Would stainless steel work? Or would grade 8.8 or 10.9 be better?

 

Also could someone double check the length for me? I only have the old bolts for the flex plate.

When I converted my 95 HB to a 5 speed, I had to replace the flywheel bolts because they were different lengths, I got them from Courtesy Nissan. I have a V6, 4X4.

 

I can't comment on what type bolts you should get but if I remember, the torque on the flywheel bolts was over 100ft/lbs. The OE bolts weren't that expensive.

I had to go get the inspection plates so in the process I just kept the factory bolts from the donor. I'll measure them and see what the actual difference in length is. I'm hoping to get the auto transmission out today and get everything under cleaned up and ready for the 5 speed to go in
