Can anyone tell me where to get a set of bellhousing bolts for an 87 na 13b? Or the thread pitch and length needed? I checked the bolt guide, but can't find the bellhousing to motor bolt sizes and lengths.

If you can find the lengths required, IIRC they're all 10mm x 1.25 . If you have a local hardware store that has a good selection of bolts, buy some grade 10.9 from them. If not, I recommend https://www.belmetric.com/ . It sure beats spending 4x the price on the same thing but in a Mazda bag. A junkyard works too if you have a local pick your part. Do pay attention to the torque spec in the FSM.

 

Maybe LYGER has some?.(you'll have to PM him)

 

Okay a member messaged me and said he had bolts, he is sending them out today. But now I have another question, what grade bolts should be used for the pressure plate to flywheel? I found the master bolt list that said m8x1.00-24mm. Local fastenal has 4 choices of m8x1.00-25mm. 3 are 8.8 grade, some regular, some zinc, etc. Or they have 1 10.9 zinc bolt.

 

I would try and help you out with the pressure plate bolts as well but I have a OS Giken set up and can't confirm the stock quantity or size for you

 

Well I know they're m8x1.0-24mm. I'd have to go look at my pressure plate to know how many though.

 

I've been looking on mazdatrix and Atkins. They say there are 4 short bolts and 2 long since it is NA. The bolt list only says m8x1.0-24mm. Can anyone tell me if the 24mm is the long bolt or if there is a longer bolt?
