Les..
With an Excal. body weight (should be very similar to a Classic Roadster, the CR II is 10lbs heavier now with our new additions to the frame)), small block, MustII stock control arms we use 375in*lbs in front, unless you shop in the BIG & tall dept. The difficult part is getting these rates in the MustII/Pinto diameter of 4 3/4"D spring and the 11" length needed in front with the CR tower design. We are on it at Classic Roadsters II, so we are now having them special made so no more cutting length to fit and too low of a spring rate. These are the springs supplied with every new CRII 427. Cost is $52/spring to buy individually.
We use 225 - 250in*lb in back, 5in diameter, 13in tall, when no sway bar added. Can sell you those too for the same price.
This is the sport cruiser specs! We also have an upgrade shock if you are interested. Also have coilover systems...
Hope this answers your question.
Give me a call, if you want the setup.
