172 main cap bolts

[db98]

Can anyone tell me the lengths of the main cap bolts? I know I can order some equivalent spec caphead bolts online but need to be able to pick some up as quick as possible and only need 2.

I’m also aware that the tightening specification is 20N.m + 62°, is there an actual torque figure that can be used instead?

I've always found FrogJam extremely quick if you pay express delivery. Normally next day.
Alternatively them may sell you singles or just give you the length if you ask nicely. They've always been very helpful for me.
