what are the bell housing bolt size and the 2 bolts #21 on the rear mount bottom #10

http://www.acuraoemparts.com/delray/...All&vinsrch=no

and yes i have searched and yes i looked in Common Honda Bolt thread pitch size dimension thread

 

The acura page lists #21 as "BOLT, FLANGE (14X67)", so it's M14 by 67 millimeters length. Also, the common bolt thread lists it as M14 x 1.25 thread pitch. The trans bolts should be M12 x 1.25. The lengths will probably be on the acura parts site.

 

i have a 12x1.25 die and it does not work with the tranny bolts

 

not a 12mm an M12... should be a 17mm

 

He said he has a 12x1.25 die, that's for a 12mm thread. The die size has nothing to do with the hex head size.

 

The 12x1.25 die is to small
And does any one know the size for the rear mount bolts #21
Any help

 

The part description says it's a 14mm thread, so of course the 12mm die is too small. According to the common bolt thread sizes, it's probably a 14x1.25 thread. Do you have that size die?

Helms lists the thread size and pitch, but I don't have it handy right now.

 

i tried the 12x1.25 die on the bolts that every one says is 12x1.25 like the bolts that mount the tranny to the motor and the die is to small.
for the other ones like #21 i know are bigger just do not know the size

ok i found out that my die was to small mismarked

12x1.25 is the size sorry and thanks

and the bolts for #21 are 14x1.5
