ok top 2 are 17mm head 12mm shaft, lower bolt on engine block is just hidden by the clutch slave cylinder, it is a 17mm head 12mm shaft, same on the oposite side
the bolts below the block thru the block extenders go thru a 1/8 inch steel plate then into the tranny . these are 14mm head, 10mm shaft, you "might" have to use a nut on these but its no big deal
