Following is my trailer hitch design for the '91-'95 MR2. It is made from simple 1 1/2" angle iron and 1/4 or 3/8" steel bar.

This hitch is VERY light duty, good for only 800 lbs maximum, but in normal usage, I regularly tow only 500 lbs.

This shows how it mates nicely into the bumper

The rectangular tube across it greatly increases the torsional rigidity

It uses the 4 bolts that mount the stock bumper and doesn't require any more drilling. You MUST get better bolts to mount the bumper to the car as the hitch now is sandwiched between the bumper and the car. Use Grade 8.8 or better 8mm bolts (30mm long I think, but not certain). Don't use the original bolts.

This is it separated from the bumper

Sorry it's so dirty, and a bit rusty, it has been there a while

Hitch and bumper mounted without the fascia

Sorry for the rust, car spent a winter in Michigan

This is my drawing for the hitch
