yeah im runnin them backwards or goin to try anways 
sorry guess what i meant by the spring perches is i have a TG perch that three holes drilled in it for different positions on em 
but from my mock up i did yesterday it looks i will have to move the shackle hanger forward when mountin the springs reversed.
and my toy rears are longer than yours so my front hanger distance might not be as much i would think.
Yep, I think your rears are 52s? I had to move my rear shackle hanger forward about 4", so that sounds right for you to move it.
I wouldn't rely on the perches to center your axle. You make it harder on yourself when it comes time to make your u-bolt flip kit. I just used the factory ford u-bolts and plate. Free flip kit. If you don't center the leaves on your spring perch, you can't use those.
Good luck, mayne!
