Bellhousing bolt size?

[ThisIsMikey]

Lost the bolts to where the Bellhousing bolts into my engine, and need to know what size they are. The truck is an 85 and I think the engine is an 86 or 87. G52 transmission I'm assuming. I've searched the threads and couldn't find anything. Any help would be much appreciated, thank you.

I wanna say a mixture of M12 and M14 with a 1.25mm thread pitch. Hopefully someone can answer your question with a little more certainty

I just had to replace one of mine because it was bottomed out in the block. I'm pretty sure it is 12mm 1.25, 17mm socket. The bottom 2 can stick out but the top ones can't be to long. Bought mine @ shucks/oreily

Thanks you guys for the help! The bolts that I got were M12 with the 1.25 pitch. One of the holes on the bellhousing was smaller though, so it looks like ill be using M10 on that one.
