Hey Jim (and Listers):

Regarding the hitch I fabricated for my '67 GT, it was quite a simple
approach.  The hitch is attached to the car via the two rear bumper bracket
attaching bolts.  

I removed the rear bumper and measured the span between these two points
and purchased a length of thick wall 2" square tubing.  After determining
how far below the bumper I needed the receiver to sit, I centereed the
receiver at a right angle to the long 2" square tubing run.  purchased some
3/16" thick 3" wide angle iron.  Using the mig welder (Miller 185), I
welded the angle iron in place so it would give me an attachment point for
the long tubing, as well as cap off the tubing ends.

This all sounds a bit confusing as I read this, but trust me, once you
remove the bumper and see what you have to work with, it is a very simple
project!  I chose the smallest female type receiver type hitch assembly I
could find (1", I think) and welded it at the center point of the 2" square
tubing at a right angle. I employed gussets for added strength wherever it
seemed prudent.

Having built one, I could easily build another one in an hour or less,
providing all the required materials were available.  It kinda like a
Saturday morning project.  After all the final fitting was completed, a
test drive with trailer in tow was conducted.  Everything was perfect, so
the hitch was removed, degreased, sanded, primed and painted a flat black,
re-assembled with Grade 8 nuts and lockwashers for safety.  The black seems
to help the hitch disappear from vision most of the time.  It could have
just as easily been painted body colour, too. 

I use a 1 7/8" ball on a removeable male part of the receiver hitch.  With
the ball removed, it looks very clean.  I wouldn't suggest that this hitch
design could pull a 32' houseboat, but certainly could tow a smaller
utility type trailer, a small sailboat, tent trailer, etc. I used the hitch
for a 1300 mile trip one time only and had no failures in the hitch.

If anyone would like exact measurements, I could create a complete bill of
materials and post it to the list.  I recall the hitch costing about
$50.00, counting materials, paint, electricity, welding supplies, etc., so
it was pretty low budget.  Originally I was going to have a local hich
manufaturer complete my design, but they had limited interest, since the
project was too small for them.

One of the other benefits to this hitch design is that it gives added
protection to the rear side of the petrol tank, in the off chance you were
rear-ended.  That 2" thick wall tubing is plenty rigid I'd say!

Thanks for asking the questions!  If anyone would like a Bill of Materials
and exact measurements, e-mail me and I will post to the list, OK?

Tools needed:           metal cutting saw, hack saw, or actelyne cutting torch, 
                                        4: angle grinder, 1/2" drill with 
various bits
                                        sandpaper, primer, paint
Hope this helps!
