Shine rear swaybar dimension & metallurgical advice needed + (ATTN: Ron P.)

[rapieper at yahoo.com (Ron Pieper)]

2.5" U channel, 5/8" depth, 5/16" thick.  

Can't upload to my corner of Al's space...so here's what I had written:

-qty. (4) 3/8-16 bolts, 1" long, with nuts, washers, lockwashers, all SAE Grade 8 (forgive us for
not using Metric-sized fasteners) 
-We drilled two 3/8" dia. holes in each end, 1" in from the end (therefore 39" apart), 0.75" in
from the sides (therefore 1" apart, centered in the channel). 
-For protection, I like Rustoleum Rusty Metal Primer (even though the metal was not rusty), then
some Rustoleum Hammer Finish paint.  I chose gray.  You go nuts. 
-The bar was positioned as shown on the leading edge of the trailing arm, centered fore/aft and
side/side. It was clamped in place with C-clamps and the hole locations in the bar were
transferred to the trailing arm. 
-The material in the trailing arm is not as nasty as we'd been led to believe.  You can go through
with the 3/8" drill without pilot drilling; however pilot drilling will increase accuracy as the
3/8" drill may want to wander a bit, even if the location has been centerpunched or centerdrilled.

-We then bolted the rearmost  hole first, then the forwardmost, for each side. 
-Done. 

The cool thing about this bar is that it takes no welding or other fabricating, just hacksawing
and drilling.  Ben and I wanted to make sure that anyone could build one of these, and we've met
that goal.  Also, differing rates of torsional stiffness can be acheived simply by changing the
spec of the bar...use a different size piece of channel.  We decided on the bolt pattern so that
we could go to different sizes easily, and swap bars between our cars.
