    tool for Connecting-rod caps '90-'92 90 hp Force

    I tried a 7mm /7/32" 12 point socket but it's not the right one (it catches but slips over) I've been digging through the old post to find the correct size socket & found that 1/4" 12 point is correct one. I have no problem buying tools, but I like to know if the is the correct seize?
