914 tool kit --what should be there?, And why is the round bar longer than my roll? Options

[PinetreePorsche]

I got my car ('73--yeah, and the 2nd one. a '72, too) without a tool
kit--the roll-up assortment. I found one, in pretty fair shape,
incomplete, for cheap-- it's medium brown (tone is slightly reddish-
brown) , grained naugahyde with 2 black snaps, about 14 in long,w/6 pockets
between the main piece and the slant-cut sewn-in second layer. I have
picked up tools--I now have all 4 wrenches, the double-ended screwdriver,
and the lug/plug/jack wrench (?), and the 15" round bar. A few questions:
Q1 -The handle-less socket wrench won't fit down in the recessed holes of the
Fuchs wheels--I assume the wrench, which also fits the jack, was made for the
steel or other wheels of the first years. -?? Did they make a thinner-
walled one later--or has anyone machined theirs down slightly at the
corners so it will go in the holes (presumably weakening it, possibly
fatally)? It's also too small, probably too short also, for a spark
plug wrench--could have been made longer and double- ended, you would
think. That's what I'd do if I ran the zoo (I had a motorcycle wrench like that)!
And Q 2-- My 1/2 inch round-stock bar (or maybe 12mm diameter) ia
14 3/4+inches long, about an inch too long to fit in the tool roll-- it sticks
sticks out the top. Did the bar come in a 14-inch size for 914s and a 15"
I have for 911s, or some other such mix, that would explain the non-fit
Q3: - I once found a link on some site, not so long ago, that had lots of
info--pics, even, on these tool rolls -- 914s, both 4 and 6 cyl, 911s, etc.
Anyone know where that site is? -Thanks
