ok, so i have my redline in the appropriate grades for my syncro's
transmission and front differential.  i can see the filler bolts, but
cannot for the life of me find any tool that will remove them.  haynes
shows some two-ended hex tool (looks like a dealer tool :^( ) being
manipulated with an open-ended wrench.

what are the sizes of the two hex bolts (front and rear) that would go into
the filler bolt, and is there a specific tool i can find at a hardware
store that will work to open such a filler bolt?

thanks.  i must say, getting all my ducks in a row today has been painful.
i've already been to three hardware stores in search of various bits, and
gone longer by far than i wanted to be!

gonna run back downstairs and start replacing things.
