The original message was meant for the List but I sent it to Jim Forbes only
so here is my opinion on "Humor".

Jim, I knew we missed you but I now remember all the very instructive and to
the point answers you always had to offer. I agree whole-heartedly with Jim
on the joke situation. I got enough of the "humor" on other lists, etc that
I quit for that reason. I really enjoy this list because it normally sticks
to business pretty well.

Hi...thanks for the great response to the rearend primer!

To answer a few questions...

On 3/4 tons, you might want to look at 60s-70s Ford and Dodge trucks.  They
used the Dana 60 axle, with 8 lugs.  I'm not sure about the widths,  you
will have to measure.  Ratios ranged from 3.54 to 4.56.  Chevy stock wheels
may not fit these rearends, because of the center hole being too small, so
check this before you get too far along with this swap.

Changing ring and pinion gears does take some specialized equipment, but you
might be able to do it without.  Items you will need include a press for
removing bearings, a large and a small torque wrench, the manual for the
rearend you are working on (although a Chiltons manual for older cars may be
sufficient), a dial indicator, and the usual other tools that most of us
want but few of us have.  If it sounds too much for you, ask some different
shops what they charge for the work...you might get a reasonable quote.

I think 4 wheel discs are not necessary on an old truck...after all, I can
lock up the rear wheels just fine with drums!  That said, my wife bought a
new 99 Silverado about a year ago, which comes stock with 4 wheel antilock
discs...and stops very well, thank you.  I measured the rearend, it is 6
lug, but it is very wide, at 68.5", so it is not going to fit an oletruck.
I think it's an 8.5" 10 bolt rearend.  It may be possible to shorten the
housing and get custom axles made for it, but that will cost at least
$500...not really worth it.  It may be possible to adapt the disc brake
parts to an earlier 12 bolt truck rearend, if you want to keep 6 lugs, but
again I haven't looked into the matter at all...besides, buying a 99 truck
rearendf would cost some bucks.

If you go with 4 wheel discs, you will want a 4 wheel disc master cylinder,
because discs require a larger reservoir...since the caliper fluid capacity
increases as the pads wear.

On the subject of jokes...I'd rather not see them on the oletruck list,
unless it's an oletruck joke.  I get too much mailbox clutter already, and I
already get enough unsolicited junk email that I have to delete that I try
to cut down on incoming email wherever I can.  Sorry...that's how I feel.
I'm sure there are plenty of joke mailing lists you can subscribe to if
that's what you want!

Good day, from Las Vegas (just visiting)
