Minitruck springs under FJ40

[CruzinGuam]

Hey everyone was wondering if anyone has info on using mini-truck springs under an FJ40. I know that these springs are quite common and I would to slap them under my rig. I've only seen a handful of pictures and little info on placement of perches, brackets, and etc. Here are some of the examples i've seen. I understand that minitruck springs are 47in up front and 56 in for the back and are narrower. Any suggestions?

The Stock Cruiser Springs work Very well once they are Sprung over!

Longer minitruck springs may not work for the short frame of an FJ40

minitruck rears (1989ish, OME's) are about 51" eye-to-eye when flat. FJ55/FJ60 rear spring packs are 47" eye-to-eye flat. FJ40 front or rear packs are 43.5" eye-to-eye when flat. If you've found a great way to find 7-1/2" to mount them, go for it.

I have a set of OME's on the shop floor, brand new, planning to use on the front of my FJ40...well, was...my online research told me they were 47" eye-to-eye...they aren't...arched, yes, but not when flattened. Still not sure what I'm going to do with them, but I DO have some room to push the front mount forward...

I have FJ55 rears in there now, and have run those on all 4 corners. Great choice, not TOO long, but hard to find without there being busted leafs...I have a set of FJ60 rears right now with busted mains...

again, not sure what my plan is...

i ran a set of 2wd mini-truck leafs on the rear of my FJ40 for about a year, i moved the shackle mount out to the back of the bumper......they flexed awesome but my anti-wrap bar couldnt control the axle wrap anymore and i broke u-joints almost every single time i rode with that setup

The stock early mini truck rears were about 47", with roughly 21/26" centerpin. With a bunch of added leafs (9 total) I still run them sprung under on my 40, and have for about 8 years. All mounts were stock (switched to taller ones from a BJ42 a while ago). Long shackles. They work fine but probably wouldn't bother do it again .

After the replies I've read from pirate and mud. Minitruck spring seem to be only last resort options unless the springs are aftermarket such trail-gear. Is anyone running OME FJ40 kits? The one im looking at is about 1200 bucks. Pretty much bolt on. However im looking for more customized setups especially since my FJ is a trail-rig and probably isn't going to the street verymuch. Currently Im running stock springs in a SOA configuration with shock hoops front and 12inch travel shocks. I want a setup that will allow me to run 38's (fenders cut already), 40series axles and handle the torque of my SBC.
