So in the midst of a clutch job I was removing my trans and realized I had.... 9 bolts instead of 10 between the bell-housing and engine block.
Instinct told me to just search for the bolt and get it ordered but all I can find is e12/90mm etc. Is this because these bolts are big enough to replace my missing e14?
Anyway I included a picture to maybe help locate the bolt I need. Cheers!

*Edit
Figured it all out and will save you the time of going through the thread. Buy all brand new bolts, its $30 USD... worth the money IMHO.
These are the correct bolts and the amount you need for this specific application.

You can get them at the dealer or online. Looks like the missing bolt is M12X90 Part# 23001222894

Conside changing one of those bolts that are in the light gray. It looks like the head is deformed. If you plan on keeping the car for a long time, or changing the clutch again down the road, you might have a hard time getting it off.

Okay thank you!
Sometimes people mess up the heads using an impact with the wrong size torx socket. You should be able to match up the bolt you need on real oem. Torx M14 x 90mm are the fattest and longest of the bell housing bolts as I recall. You might add some items to the order and get free shipping if there are other parts you need. Oil filters, etc.
I've always considered it good practice to renew all of those bolts. They're not expensive.

I mean theyre all in good condition but from past experiences Ill just have to take you up on that deal.
Just being sure, this is my cart on Pelican. Do these all look correct? They do to me.

One last question.. I see washers on some peoples builds. Why would you use a washer on this bell housing?

These bolts have good sized round flanges that are like a washer. I see no need for a washer. The factory does not use washers. If I was missing a bolt or damaged one and had to swap in a regular hex head or an Allen head bolt, I would use a washer.
There are no washers used on those bolts. I don't know what builds you are looking at, but look at better builds.
There's really no need to replace these bolts unless there is head damage to the etorx. The ZNS3 coating is good to renew if failed, but they are a standard bolt more than capable of repeat use. That's coming from someone who often purchases OEM hardware.
