Don't have any specs to offer, but I can definitely empathize with you and your situation. Just removing a helper leaf will still allow you to carry your described load (keep both sides even as far as the spring pack leafs and you should be fine)... without the assist from air bags. Don't know your financial situation, but might be worthwhile to look into THESUSPENSIONKING springs - they've got the best prices I've seen.
On a side note, great decision regarding your shock selection. I've been running the Edelbrock IAS Performer shocks for several years now and have been very happy with them.
