Chassis Guy/gals that understand SS Spring....Help!

When I built My Dana I was 1200 into it with mostly new parts and the same with my 8 3/4 that I blew up in 20 passes LOL..
I have installed a transbrake and a bigger motor since the car was built 20 years ago.
Gonna do the strange s60 deal. Already bought new or very little used parts. Strange yoke,4:88 pro gears, will use the 35 spline strange axles from 8 3/4, believe it or not pro form makes a very nice support cover for the Dana and it got red lettering to match my car lol. Just gotta get the s60 housing.
