I would skip the longer shackle and go with a set of Old Man Emu springs for the rear, especially if you are still running the Northwest Off-road rear springs. I ran a full set of their springs back in the day on an '81 pickup and I can honestly say that they were the harshest riding springs I have ever ridden on! They were so stiff that they barely flexed on the trail! Had them on the truck for 3-4 years and they never got softer.
I now have the Old Man Emu's on the rear of my '89 extra cab pickup and can't say enough good things about them. They started out at around 2"-2 1/2" of lift and settled to about 1 1/2" of lift. I've had them on for about 4 years now and consider them to be one of the best bang for the $ mods I've made to my truck. They ride nice and flex well.
I started the rear suspension of my truck with worn stock springs and longer shackels to gain some height and it rode kind of harsh. The OME springs fixed that problem. Worth the extra couple hundred dollars.
Don't know how to post a shortcut to my build page but if you go to my page I did a little write up a few years ago on what a budget suspension for our trucks can do.
Glad you decided to fix up your truck instead of getting rid of it!
Thanks for the input. I'm glad to hear from someone that had the Northwest springs on. They are very harsh. But throw 800 lbs in the back it rides like a dream. lol. It also comes in handy when Ive had a ton of crushed asphalt to haul. But for everyday driving man does it suck. I wish they had a spring that was a good 3" taller as mine increased 1.5 over stock and really should be higher. Not sure if it would be the right thing to go OME and then add a longer shackle as mentioned before or add a 1" block or go with something like skyjackers softride 4" leaf springs.
