56f100 MII question

[z65mm6]

Need some help with a project.
Reading some of the recent threads piqued my interest, but I didn't want to hijack someone elses thread.
this started out as a MII that was widened by 4" between the control arm mounting points
I narrowed the LCA mounting points by 4 "(stock MII width)
The UCA mounting points I lowered by 1"
The LCA's were lengthened by 4" and measure 17.25"
The UCA's were lengthened by 2" and measure 9.9"
this is the resulthttp://us.a1.yahoofs.com/users/432b9...A4AMEBLUJGikT2

the above was generated assuming a roll of .8 degrees
the arms were lengthened to help with scrub radius (-1.20")
I'm wanting to run a 26" tall tire on an 8" wide rim.
I'm thinking of an offset somewhere around 50mm.
Overall this should increase the height by about 2 inches over what I think ford originally intended.

The roll center seems high but I'm wanting to run a 406 FE. that coupled with the taller body of a truck I'm guestimating a COG of 30" so I'm hoping that will work to my advantage.

Where might I go with this, what else might I think of changing. This isn't intended to be a corner burner by any means, the closest it might get to the track is a support vehicle.

From where it sits now the rack will have to be somewhere around 7.5" wider than the stock MII rack to accomodate the mentioned changes.

Another avenue I was thinking of was leaving the UCA's and mount alone and just narrowing the lower mount and increasing the length of the LCA's but I think that would have negligible effect on geometry.

Thanks for your help
