Would HD rear leaf springs require longer U bolts?

[Iguana]

Hello,
I just ordered heavy duty leaf springs (6 leafs) to replace the standard rear springs on my 72 Challenger. Does anyone know if that will require any change in hardware, such as longer U-bolts or anything else I should order ahead of time?
Thanks

I do not believe that new U bolts (or better said longer U bolts) are needed, typically there is ample length to use them. That said, I generally always replace the U bolts just for the piece of mind.
