Front Diff Mount 17mm...diff mount to Subframe 17mm
Driveshaft and Half shaft bolts 14mm.. rear Axle Nut 34 mm..Flywheel Nut 2-1/8inch or 54 mm.

Pitch would be helpful with those. I'd assume they're standard and as such are probably 1.50 but can't be certain.

I need Front diff mount thread and pitch info.

Was 1.25 not correct? If not, you're probably right assuming its 1.5. I would pull one off tomorrow and tell you but I've got my sister's wedding to attend.. if you dont find the answer by sunday night I'll find out for you...

I don't know off the top of my head. I tried using an M8 by 1.25 (I think, may have been an M10) but it was too small. I ended up finding the missing nuts caught in the mount itself. Talk about lucky. Now I'm going to go find a shop that can get this taken care of today... hopefully. I don't feel like dropping my subframe at all...

christ this was a big help to me as a beginner haha. THANKS!

I need to know what size the nuts going on the lateral links into the rear subframe.

Anyone know the bolt size & pitch of the two on the front cover of a TII, underneath the CAS? Looks like a 12mm but I don't have any bolts to try in any pitch.

Bolts for the front oil cover?
Yes, they are all 12mm *hex head*.
5 or 6 of them in total in differing lengths?
12mm hex head are 8mm *thread diameter*.
So it's 8mm x (pitch).
Typically 8mm thread pitch is 1.25, but it could be 1.00 or more rare 0.75.

Thanks a bunch for the reply, Ted. However, that's not the bolts I am looking for. On the driver's side of the front cover, directly underneath the CAS, there are two bolt holes. These are the ones I am looking for. I believe the two holes were for an A/C mount or P/S mount.

These are two big bolts, approximately 12mm bolt size, not head size.

Ah, the ones off the bracket that normally holds the A/C and (optional) power steering pump?


-Ted

[jtbshaw]

I believe that is correct Ted.

Here is a pic (the two directly underneath the CAS, may have been studded from Mazda):

[RETed]

Yeah, if you are asking about the two "missing" fasteners that's in the aluminum part of the bracket - right in the middle of your pic - then those were originally studs.

You still want the thread pitch and diameter of the studs?


-Ted

[jtbshaw]

Yes, I would still like to know the diameter (size) and pitch of the studs?

[RETed]

The "outside" spec is 10mm x 1.25.
I hope the inside thread is the same...

This is the typical 10mm pitch.
Only the exhaust studs are 10mm x 1.50.
The oil metering "valves" are threaded 10mm x 1.00.

FYI: Bolts for body in/around engine bay are 6M-1.0mm Length unknown, but I have found 12mm full and partial threaded that would suffice. These include the front mounting location of the bumper skin, fenders, etc. I am assuming the lower threads are identical but haven't checked.
