I was born and raised in Winslow Az, my grand parents also lived here and had a home and tradeing post near Williams Az in Valle about 20 miles North. As a teenager i would go to Valle and work for her at the tradeing post during the summer breaks. She owned a 1966 Nissan Patrol that she called "THE DATSUN" every mlrning we would get in "THE DATSUN" and drive on the side of the road about a mile to the tradeing post. The reason we drove on the side of the road was because she had 2 German Shepards (Shane and Shawn) that would run behind us all the way. Wow the memories! That was in the late 70s early 80s. My grandmother loved "THE DATSUN" we would always go 4x4ing in it in the forest to go arrow head hunting. We also took it to Williams Az to go grocery shopping all the time, i am looking forward to takeing "THE DATSUN" to the Route 66 JDM Classic since its held in Williams Az (how cool is that!). In 1984 my uncle (her son) talked her into replacing "THE DATSUN" with a new Jeep CJ and he took the Patrol to his Tradeing post outside of Flagstaff where he used it to plow snow for years! My grandmother never did like the Jeep, it just didnt measure up to "THE DATSUN". she passed away in late 96 and my uncle asked me if i wanted "THE DATSUN"? Of course i said yes. I finally picked it up around 2004. The motor ran, but it needs rebuilt. I had a Chevy 292 laying around so i stuck it in "THE DATSUN" it runs pretty good! One day i opened the glove box and what do you know, there were several arrow heads in there, possibly from when i went with her years ago! I left them in there, thats where they will stay! I love this old Nissan Patrol "THE DATSUN"! I now have 7 of them, the other 6 are just parts donors. I am now building a custom Nissan Patrol pickup. The cab roof and back are all custom built along with the bed. Its mounted on a 94 Jeep Wrangler chassis that i extended 18" and installed a 6.5" lift with 33" tires. Wish i could post pics of these, but i cant figure out how to do that. Anyway, i will also call this pickup "THE DATSUN".
2" to 3" blocks are no problem with all the springs present - especially with the stock engine. This has been done for ages without problems.
Sure, manipulating the springs by a reputable spring shop may be better, but blocks are sufficient (an unreputable shop will cause nightmares). Depending on how low you want to go, 720 4x4 spring packs will lower the truck about 1-1/2", so that and blocks may be a good, easy combination.
NOTE: If you're installing them like the pic above, make sure to cut the U-bolts. You should never have any part of the truck lower than the bottom of the rim (larger rims help).
