Freeze plug issues

last week when i put water into my radiator, i noticed i had a dribble coming from the rear passenger freeze plug, so i pulled the torsion bar and steering linkage and unbolted the tti header and am letting it dangle loose in the fenderwell. well i popped out the old freeze plug and while trying to get it out lost it in the block... oops, anyways put new freezeplug in and im having the same issue, still dribbling, i dont think its a bad freezeplug issue, more so it seemed like there wasnt quite the taper on the block, where this freezeplug goes in compared to the others, at least it seemed like the others had a taper.... what should i do? ive heard of heat cycling the motor a few times and it may solve the issue, but if its dribbling this bad now i cant imagine once the water pump is going and the system is under pressure.... any suggestions? jb weld? idk im kinda outa ideas and frustrated... really wanting to fire up this motor ill take any suggestions, thanks fabo!
