I just finished putting new 5 leaf springs from Springs and Things on my 68. http://www.espo.com/ I must say I am very pleased with what I got, top notch stuff. I also went with the Gteck 1 1/4 solid front sway bar and 1" solid hellwick on the rear, coupled with a set of Billstein shocks all around... The ride is unreal, the handling is awsome... Its like riding a slot car.....
