What length bolt did you end up using--- Getting ready to install a M63 HV on my build.

I purchased all grade 8 bolts. One @ 5" and cut it down to 4.75" and three @ 3". cut down to 2.75" as my hardware store only had bolt sizes in 1/2" increments.....With lockwashers, this gets the bolts threaded into the block 5/8".

I "trimmed" about 5/16" off the long bolt. I measured and it was too long and bottomed out. The other 3 were fine.
