Bolt size - xflow engine

Has anyone got to hand the details of the thread pitch and bolt thickness for the top 2 bolts which secure the bell housing from the gearbox to the engine?

I think they're 3/8ths UNF but need to get a couple of longer bolts for the engine stand and would prefer to get the right ones second time (wrong ones first) and I left the damn bolt on the worktop this morning 30 miles away!

I think they are a UNC thread iirc - the rest of the bolts that screw into the box not the head are metric though

Yes, they're 3/8" UNC.
