Good points, Dave.
Do you know what all goes into the Allpro conversion?
I've read their catalogue page a few times, and it feels kind of vague, but it seems like a combination of their proprietary front hanger and some in-frame shackle mounts for the front springs, but do they also relocate the hangers for the rear, too?
I think the stock first-gen rear spring angles are a little harsh, so I'm wondering if they had a solution cooked up for that, too.[/QUOTE]
All-Pro, Trail Gear, Sky's Off Road and I believe Ruff Stuff all make a similar front Hanger. It welds on to the front moving the hanger about an 1" forward. This helps keep the larger tire in the wheel well and makes room for the longer spring, With larger tires you can clearance the fender pretty easily if you need to.
The hangers for the rear springs moves and have to be welded on.
The emergency brake line also has to be relocated 9 not difficult, and a hi-Steer Kit is recommended.
The catch to the lift from All-Pro and Trail Gear are welding is required if you don't weld then you need to find someone that does. Plenty of Shops around and people that do it as a hobby. Though you want to make sure the people are experienced welders. I have seen bad welds fail, but then again, I have seen good welds fail.
Here is the link to the instructions on All-Pro's web site it is in their Tech section

The extreme Kit requires the IFS box and a plate (plate included with kit).
To be Fair here is Trail gears-

And Sky's
Toyota 5 Inch Lift Front Leaf Springs - Sky's Off-road Design front hanger
Toyota Basic Solid Axle Hanger - Sky's Off-road Design no install instruction on web site.
All of the above companies support the off-road community and access to trails. All support TLCA events.
I have some trail gear parts, all pro parts and Sky parts on my mini truck.
My nephew's truck has Trail gear springs with Chevy 63" outback. Come to Fun Day this year and you'll get lots of opionions on which is best.
There are inexpensive way's to lift a mini with out buying a Kit even if you buy springs from one of these manufactures.
