C20 Moog coil spring replacment options.

[Chilly178]

Hello I'm looking to replace all four coils on my 72 C20. I'm looking at the Moog springs specifically. https://www.moog-suspension-parts.co...20_pickup_1971 I've already decided I wanted to go with a constant rate spring. So that leaves me with two options for the front and back. Standard and HD springs. Moog 6102 vs Moog 6104 for the front and Moog 6101 vs 6103 for the rear. I'm wondering if the HD springs will make the truck sit higher or lower than the standard in the front and back. Which ones should I go with? My truck doesn't have the spid option for the heavy duty springs so i'm thinking I have the regular 3/4 ton springs. Thanks.
