I did a search on this site and all over the web to try to find the information I need but could not so I'm going to make this post. I want to know the size bolts that are used for attaching the tranny to the block on the D16A6. The Hayne's manual I have for the car said M10 but didn't mention thread pitch or... anything really, other then M10. I bought the M10's that looked like they'd be suitable and now here's where it gets interesting: the M10's I bought only fit right in two of the holes, they were too small for the other holes. Are there different sizes for the other holes? I'd appreciate it if someone could point me to a site that could tell me more or if they knew, they'd post it.

 

I just bought some yesterday.The other holes are M12's.

 

Do you know what the thread pitch is?
