69 Chevelle SS Front Springs

[sixt9rsx33]

I am replacing the above in my SS and the car does NOT have F41. I live in Charlotte and go pick up Eaton Springs from NPD, but they only offer the heavy duty front springs. I looked on Rock auto and they too only offer the front heavy duty spring. I want to make sure the spring pocket on the control arm is the same for both heavy duty and regular duty springs. Is it ok to put a heavy duty front spring on a regular duty control arm.

Thanks
