I've got a 97 Gulfstream I need to add a receiver to....... assuming these
are good quality welds is that all that's involved for a  receiver?
Does  anybody have experience with removing the bumper and creating they're
own  tow bar mountin?<<<<<<<<<

The receiver on the Gulfstream will more than likely have to be fabricated
because I doubt someone has a receiver sitting on a shelf that would fit.
You will need a tow bar so when you buy one, see if you can get a mount for
the Wrangler with it.
Then look in the yellow pages for a welding shop that fabricates/installs
hitches.
Take both vehicles there and have them install whatever is necessary.
Any competent welding shop will make sure the welds on the added channel are
sufficient.
Unless you are a welder, trying to do it yourself would be foolish.

Jeff,
If you look at the Roadmaster towbars, many and particularly the fold up
one (mine is older and I don't remember the new model) have or can be
fit to quick connects that can be bolted to a Jeep front bumper - if it
still has one under the plastic.

If you have welding equipment handy, making your own tow hardware is not
too tough.   What is great is that there are three manufactures with
good websites (Roadmaster, Blue Ox and Demco (sorry no links handy).  If
you search these you can often deduce from their pictures/instructions
how their brackets/baseplate are constructed.

Roadmaster has a good collection of brackets to later mount that tow bar
on what ever you choose (except in my most recent case where the catalog
part didn't actually fit).

And think about brakes......
Many states now require a brake away feature.

You will have to get a "universal" receiver that will expand to match the
spacing of the frame rails. Then just bolt or weld it on (that's all they do
at the factory).  I know Reese make a universal, and I'm sure most of the
usual suspects do too.
