Does anyone know the size of the nut that fits on the bolt circled in Blue in these pictures and the bolt that fits into the hole circled in purplish? I need these in order to use my engine stand adapter and I am tired of hitting the hardware store only to come back and the bolt/nut be incorrect. Any help would be appreciated.

 

12mm by 1.5 maybe

try one of your lugnuts on it

 

Since it holds the A/C bracket, why not take the A/C bracket bolts to the store with you to find a match?

 

i think its the same as the lug nuts...at least it is for the FC.

 

I dont have the brackets for that motor. That thing is just a blown junk motor that I am tearing apart and will practice porting on. If its not a horrible pain, I will take the bracket off of my car and try that. Thanks!

I tried lug nuts they wouldnt work. I may have used the wrong pitch lugnut but I dont think so. I will check again tonight.

 

use a pitch gauge to check the pitch

 

IIRC the stud is m12x1.5 and the other two threaded holes are m10x1.5 or 1.25.

 

Goodfella -- You were right on. Thanks for the help!

 

Just as a future reference it's m10x1.25 and it should be 25mm long

lol, wish I had that now I have to drive back and change them out -.-

 

No problem
