Re: 66 Scout suspension Questions
I have a '71 Scout in my garage that I'm planning to make a rockcrawler out of. I had the suspension all planned out until I broke out the measuring tape. I was planning on running wagoneer springs up front, and 2wd chevy rear springs out back. The 2wd chevy springs are 60" long and flex like crazy. However the Scout doesn't have enough frame to mount the chevy springs with out moving the center pin more then I'd like. The Wagoneer springs will barely fit and also have a good reputation for flexing. I was planning on running Wrangler springs with a full length add-a-leaf front and rear, but I asked local Scout authorities and they said that the Wrangler springs will NOT hold up to the Scout's bulkitude, the spring rate is just too low. The shop I talked to uses the wagoneer springs up front and stock scout 2 rears springs on their scouts (they have ScoutIIs but 800s are roughly the same size). Their scouts are flex monsters.
However the Scout 800s won't flex as well as a Scout 2, their frames are wider. This creates several problems, first off is the tires getting in fights with frames. This is one of many reasons why you need to ditch the stock axles. You could use Scout2 axles but they are difficult to find and setup oddly which makes it hard to perform spring overs plus have 0 degrees of caster. My choice is to run a Wagoneer front 44 and a scout 2 rear 44. The Wagoneer front ends are cheap, plentiful, easy to spring over, have good steering from the factory, and 7 degrees of caster. As an added bonus if you swap in the wag front end and decide to bolt in a full width chevy or dodge axle later the springs don't need to be moved.
Unfortunately I am broke and can't afford to play with my Scout right now but here's the run down of my plan. 345, wide ratio t19, dana 20, Wagoneer front axle and springs, front end sprung over with shackle reversal, scoutII power steering box, ScoutII rear dana 44 full floating with discs, full bumper to bumper roll cage with seats seatbelts and front clip mounted to it, and some rear springs I haven't decided on yet. I'll have to spend some quality at the junk yard with a tape measure and pick some out.
Building a good custom suspension is mostly trial and error, expect to do it more then once before you get it right. Just try to get the longest springs you can fit off a vehicle of roughly the same weight and it'll be a good starting point. As for the the spring over/under issue it has been debated elsewhere and obviously I lean towards the spring over side. My friend had a 69 scout 800 he kept spring under and it barely cleared 33s and flex was minimal. As for the buggy leaves I'd say don't bother. The front of the scout would make it pretty easy to do but your only going to get so much flex before your tires hit the frame unless you run full size axles. I could go on forever telling all the things I've learned over the years building suspensions but I'll stop here. feel post any questions and I'll answer when I get a chance. Best of luck on the Scout, I'd love to see another fridge on the trail.
