cheap suspension for short course off road race truck

[alwaysFlOoReD]

Hey, hope someone has some insight. I'm trying to figure a cheap way for more travel on my short course truck, and this is my idea so far;
I have an '80 full size bronco that I can use for parts. Take the dual shock coil bucket and mount it to my '91 Ranger [with stx drop brackets and extended rad arms] short couse off road race truck. Use the springs from a '66-'79 f-150 that's under 6350 gvw, they are slightly less load rate and spring rate as the ranger but 4" longer. Gives me more travel and more shock. Anyone see any problems?

'91 ranger; i.d. 3.5" / bar dia. .671" / install ht. 10.5" / load rate 1447# / spring rate 430# / free ht. 13.75"
'66-79 f-series
under 6350; i.d. 4.0" / .671" / 13" / 1330# / 271# / 17.5"

From the numbers it looks like the f-series is less stiff than the ranger.

also,some of the rules I'm running under;
one 2.5" shock w/res or up to 4 - 2" per wheel
no coil overs
allowed to move susp. points as long as length stays the same
12" max travel metal to metal

Thanks in advance,
