rear trailing arms ???

[yenko/sc]

Im looking to do a nascar truckarm type rear suspension on a 1964 ChevyII nova hardtop. I was wondering if anyone here could help me with some diminsions on the 60-66 and 67-72 rear trailing arms. Are the rear arms different lengths for different years or do they all use the same length arms?? And can anyone help me in finding some good condition arms possibly. I know i am a car nut but ive always wanted a 70 dropped swb/bigblock parts hauler!! And if it ever happens it looks like i found a site to get all the info ill ever need!!! great forum!! Appreciate all the help i can get...Cliff
