OK, back on topic...
i added a better description back on the post w/ the new pics for those who give a crap.

i'll get one after i get the carrier completed... the tire's on there just for fitting it up. i still have alot to do to it, and then i have to clean it up. i've got my work cut out for me to get it finished by Wed nite/Thur morn when i'm working until then. the carrier is currently pulled w/ the wheel and jack off and sitting on the garage floor. i hope to get the rest of the holes tapped for the latch and the HDPE support plates so i can leave it on to finish it up.
it's just triangulated like /\ w/ the carrier hub plate at the top on a 2" square tube like before. i notched the top of the /\ for the 2" square to fit in the notch and then welded it all up. it's got the gussets at the bottom, and will eventually have a crossbar to snug the tire up against and some plate at the top on the backside as a gusset for the top. the support arm for the hi-lift extendes off the top of the /\ out about 7.5" and there will be a plate on it w/ a hole for a bolt and wing nut to secure the jack. there will be another bolt and wing nut on the base to secure it there. the 2" square tube that the hub plate mounts to is directly in front of the toyota oval on the back gate to give you an idea of placement. that's a 285/75-16 MTR w/ about 8-10k (your old spare) on the spare wheel.
here's the other verbage and pics for reference again:

here's the other verbage and pics for reference again:
cut up the old carrier and salvaged the main beam and the hub plate. fabbed up another tire carrier out of 1.25" SCH40 pipe and the tag bracket out of 0.5" SCH 40 and got it on along w/ the hi-lift mount. the tire is now lower and tucked into the body more, but there's still plenty of clearance. i had to make a jig for the carrier frame cause the pipe doesn't run verticle when looking at it from the side. it actually angles outboard slightly away from the body and also triangulates to support the carrier hub plate - that was fun. it was worth it, cause now i have the look i want and didn't compromise on strength. the 2nd gen tag bracket will completely cover that pipe frame, so it won't be visible at all. the hi lift has the base plate, then an upper support that you can't see behind the tire.

the old one IMO was too boxy and too busy. it was distracting. i really like the simplicity of this one. too bad i wasted all that $$ on that square tubing and cut it up...
oh well, i'll use it on something. 
yeah, working real hard - almost as hard as you work M-F.
about to go out in the plant to verify valve positions as they bump them from the control room... oh fun oh joy.
that 80s a good deal if it's in decent shape...

Looking great!
Not sure if you want any more constructive criticism, but it looks like you could still lower the tire a few more inches without affecting your departure angle. I would either lower the tire a little more or angle it back like rockota recommended. Something to get it tucked a little tighter to the vehicle.

thanks. only thing i'm not happy w/ is the hub mounting plate for the spare was cut out w/ a plasma and it wasn't lined up exactly right, so it's a little skewed. i then didn't catch it when i welded up the upper support for the hilift, causing it to tilt since i was comparing it to the plate and not the rest of the frame.
i can fix the hilift bar, but the plate is on there for good. the good news is that it is all hidden when the spare's on there.
i still need to add a lower crossbrace on the /\ support so that the tire snugs up against it when mounted and then i need to drill the holes for the bolts that mounts the hilift.

Hey Andy, do you have the technical plans and drawing available for this bumper? I would love to see what it might cost to have my own built minus the tire carrier. What might you estimate just the bumper costing?
#177
yeah, i have the cad drawings that scaled measurements can be taken from. that's how i built this one.
i guess it would be about $150 in materials for just the bumper and then add in about 15-20 or so fab hours at your local rate - probably about $40/hr or so. it will be in the neighborhood of $1000 to pay for one to be built.
for the carrier, you have another $300 in parts, $50 in steel, and another 10+ hours in fab time. since i had to figure things out as i went and also change the carrier frame, i have about 60 hours in this one, but it was also a learning experience.
i also have about $100-$150 in consumables like sanding/grinding/cutting discs and welding wire.

there's a lot of time in there to prep that rear main rail to get those angles in there. the sides are pretty much cake.
those compound angles are the hardest part.
want one cheaper? get a welder off ebay for $300. get some steel and practice a bit. buy your bumper steel, a 4.5" angle grinder, a 10# spool of 030 flux wire, and some misc grinding/cutting/sanding discs and do it yourself. when you're done, sell the welder and grinder and get most of your money back.
this is my first fab project ever - but the degree in engineering and experience in project management and execution helps, but isn't necessary. that just gave me a head start and the ability to rely on other people who do this every day for advise.

Thanks for the idea and vote of confidence.
