single pigtail springs fit on rear axle housing pigtail down with no modifications at all, been running them that way for years, is that a problem now?

Nope problem is cars already dont have stock spring perch on rearend that were considered illegal now they can leave them and not have to put stock mounts back.

Thank you Bobby and Chuck. Language has been corrected.

This very novice team is doing a great many things right and naturally also making a few errors here and there, but learning each and every day.

I'm trying to clarify this. Yes wording has been updated but now they say two different things right?

 

If you have to run a pigtail spring on a stock perch then the part about

 

non adjustable spring bucket on rearend needs to be removed, Bc it has to be a stock perch on rearend nothing else?

 

Thanks

DANIEL

The way I read it is you can use spring spacers. They can not be adjustable. I use spacers on my front and rear to help put wedge in a leaf sprung car. Useing different spring rates doesnt allow the desired cross weight without haveing a ridiculously high spring rate split. On Metrics, it may also be desireable to install a "NON ADJUSTABLE" Spring spacer on the springs front and rear while maintaning stock mounts and perches. They are trying to keep these cars in the stock mount formation while allowing us to still tune the car out of a wreck. Still dont see any grey here. JMO. but have been proved wrong before. K.I.S.S
