I figured out an easier way to calculate were to put the front spring hanger on a chevy swap.Here is what I thought.
The stock rear Toyota 4x4 springs until '88 were about 48" long with an offset center pin. Meaning that the rear to center pin is 27.5". And center pin to front of spring is 20.5". Now considering the chevys are 63" long with a centered pin. So from rear to pin it is 31.5". Same for the front too. Now take the 31.5" from the chevy spring and minus that with 20.5" from center pin to front of Toyota spring. 31.5"-20.5"=11" You get 11"! That is were you place the new hanger to get perfect stock location. Simple huh? Hope this helps people. <IMG SRC="smilies/smile.gif" border="0">

If you notice he wasn't educated in California, so he can do complex mathematic formulas! <IMG SRC="smilies/biggrin.gif" border="0">

but does the calculation take into affect on how much arch there is in the spring and what the tire will do and sit when compressed into the fender well?? <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0">

He'll figure it out, if he ever does it? <IMG SRC="smilies/rolleyes.gif" border="0"> I did all the pre-weld measurements, and the tire still ended up about an inch to far back from where I wanted it, when everything was said and done. But it works fine. <IMG SRC="smilies/tongue.gif" border="0">

LOL. <IMG SRC="smilies/biggrin.gif" border="0">

However a lot of times, there is a difference between theory and real-world. <IMG SRC="smilies/tongue.gif" border="0">

If you move the mount forward 11", the axle ends up moving back a bit, but it will be centered in the wheel well when the tire stuffs, which is how I wanted it.

I did the math first, and then fitted everything up to see where things would actually end up before settling on a final location. <IMG SRC="smilies/idea.gif" border="0">

The true easy way is to just copy how other people have done it. <IMG SRC="smilies/clown.gif" border="0">

U R overthinking this, I told you the plumbob was easy, way easier then the headach i just got reading your thread <IMG SRC="smilies/biggrin.gif" border="0">

 

[liftedwithleather]

ok ok ok........... <IMG SRC="smilies/clown.gif" border="0">

 

[ToyFamily]

I did that comlicated math <IMG SRC="smilies/smile.gif" border="0"> on my first spring swap for mazdas and it turned out fine. Then when I did the chevy swap I just mounted them up and centered the wheel in the wheel well (eyeballed) the only time I measured was to square it up. It turns out when I flexed it up I had an 1/8" on either side of the wheel well <IMG SRC="smilies/eyemouth.gif" border="0"> , guess I got good eyeballing skills <IMG SRC="smilies/tongue.gif" border="0">

I used a plumb bob to do mine and never paid much attention to the stock hanger, So I just went out and measured, CE to CE is 11.25" forward. With 35s at full stuff it looks like I could have gone another 1/4" forward to center it exactly. I think 11" would put your axle to far back, unless you only plan on running 33s.

So much for your calculations <IMG SRC="smilies/thefinger.gif" border="0">

 

[xextr3m3]

I took the standard answer of 11"s and then moved it a smidge(it a word now <IMG SRC="smilies/biggrin.gif" border="0">) forward
