Default Bolt sizes

I was under my car changing the fuel filter this weekend when I noticed that I had 2 bolts missing on my transmission. 1 that bolts the bellhousing to the engine block, and one that bolts the transmission to the bellhousing. Does anyone know the sizes/thread of these bolts so I can go pick them up and put them in. I'm not sure if they backed out, or if they were never put back in when my clutch was installed.

TIA

Bellhousing to block bolts are 13 mm, don't know the length. Transmission to bellhousing bolts are 15 mm, don't know the length.

Go to a dealer and get the right bolts. Take one of each out to use as comparison. It'll be worth the money to have the correct bolts.

I was wanting to know the actual sizes of the bolts ... but I might just run to the dealership and buy them there for the convenience of knowing they are the exact bolts needed. I'll pay the 100% markup there ... and pay $3 for 2 bolts

Without a doubt they use way more than 100% markup

The distribution center gets 40% and the dealer gets an extra 40%.
