Opinions on rear spring idea

Who's the dealer you got them from? I might go that way it's a little over my budget right now but might be better in the long run "pay me now or pay later" kinda thing.
Thanks
ps where in Ontario are you?
The dealers name is Lockwood Chrysler in Oakville,Ontario.They ordered from the Mopar Performance cataloge,the one came in 3 days,the other was a month.This was right when Fiat boughtout Chrysler,so they were leary about ordering parts.I hope this is all behind them now and you can get an order quickly!

Part #p4510269
#p4510268
I did get these at jobber cost of $149.95 each.Good Luck!
