Probably best to simply measure it with ruler or calipers. If
original bolts, SAE units rather than metric. Measure flat-to-flat
across the Allen hexagonal.

Hello All,
I recently joined here and have been gathering and learning a
lot.?
I have been fortunate to acquire a GM8 with the 492 direct drive
unit and an extension installed between the tripod and the
head.?
Does anyone know what size Allen key is needed to disassemble
the bolts?
?
Pete?
