yes put 12 on each side dab of grease will hold em in lookin good ! TIP allways blow out all that grease and put plain oil on them IF the needles do not rotate they will get FLATSPOTS on them , the needles that ride on wrist pin are bad on sticking (not rotating) then it all heats up then BOOM ! if you run pure caster oil & alky , the caster can gum up when the engine is in storage and them needles will not turn free BOOM , when you buy a piston off the shelf CHECK to make sure the needles are turnin free ,some are hell to free them up ! Soak piston in laquger thiner or that stuff that helps to unscrew rusty bolts heck ya may need to heat them up carefully / if the wrist pin is in the piston and needles are stuckj it can be hell to get then neeles free take care keep at it v!
