      It was certainly a lot of work for sure, thanks for the praise!

      springs

      Dont know if you mentioned or not but did you use YJ front or rear springs? I think the fronts are 4 leaf and rear is 5 leaf but not sure. Also did you use shackles from rear of a ranger? All i need is a set of springs and figure what shackles I want to use and Im ready to start my sas project!:thumbsup:

      I used rear 5 leaf, but as I mentioned they were not enough to support the heavy BII front end. I took another set of YJ springs and cut the main leaf eyes off, I kept it long enough to support the original main leaf under it's eye's. then also added a second "second" leaf under the second one (did I make sence?) I left the spring clamps open so that the leaves could fan out when drooped, it works very well. So what you end up with is a 7 leaf spring pack. As a side note, we are selling gthe Teraflex fiber leaves because there is no use for them. We are looking to get $300 for the pair and they would be the better way to go. Our problem is that I would have to remake the spring mounts on the frame to make room for the Teraflex's larger spring eye's, they use spherical ball ends instead of rubber. These leaves have incredible flex when in YJ's, and should do as well in the BII. I used Cherokee 2" lift rear spring shackles because they worked with the frame mounts I had access to. YJ shackles are more desired because they offer more lateral stabilty, but this is seldom driven on the road and so we put up with a little softer steering.
      Re-read my posts and you'll get a better idea of what I did, it may not be what you do and you might come up with some better idea's. Either way it sure spanks the TTB any way you look at it!

      tera springs

      Hell yea it does. Thanks alot for the info should help me out if I go that rout. As far as the tera leafs you have Im very interested but would have to try and scrape up some cash,so if we could work out some kind of pick up or shipping I would be willing to get some cash together if you really need to get rid of them. Just let me know on how long I might have to get some cash but I really want to try and get them;) thanks and let me know, Ill put them to real good use:salute: haha

      If I can get the leafs Ill be able to get the swap done this summer and you will have to let me know when you will be doin some wheelin maybe we can hit some trails and check the rigs out

      Shipping shouldn't be much, they are very light weight. We paid over $400 for them, he'd take $300, not a rush though whenever you get the cash.

      It's the same as for a stock YJ spring. We can't use them because the rear mounts that I made using Ford hangers aren't deep enough and the outer part of the spring eye is larger than the JY factory spring. We didn't want to go through the hassle of remaking the mounts. If you started out with the Tera leaves in the first place then the mounts can be made to fit them right off.

      This is exactly why I love my little B2. Dirt cheap to work on, easy to work on, goes just about anywhere, and it's timid enough I can let my girl drive it without killing herself or my rig!

      Edit: Just out of curiosity, what springs are you running in the front of that B2 again? I think I'm just really slow, because I can't find any specifics. Also, what size tires are on it in those youtube videos?

      The springs are rear Jeep Yj leaves with another main and second leaf added because the BII is so much heavier than a Wrangler. As you can see though the BII flexes well with 7 leaves, rides very well too.

      Yeah, I'm pretty much a dumb-ass. I re-read it and found the answer. You talked about the new springs and how you hoped they didn't sag also. Did they? Just curious...

      The springs have not sagged a bit, looks like they will work just fine.

      Nice. I'm hoping I can decide what I wanna do with my B2. Keep updating this post! It's nice to see people's projects working.

      Looks good! We thought about an XJ front but thought there might be clearence issues with the oil filter, no one had done an SAS on a BII that we could find at the time.

      Axle Swap

      I would like to see how you did the swap, I have an 84 as well and was trying to decide what I should do with the axles. I just got it so I don't know where to start.

      Not sure what you mean, did you follow the thread? I'm pretty sure most of the pics still work, but a lot are dead links now.

      Ok, we finally did it! Taz now has a 4.0! Yes! Daniel finally returned home from his 4 years in the Navy and it was his dream that kept him going while in the gulf to swap in the Explorer 4.0. Through Nov and Dec we took a couple of Saturdays (and many long afternoons sorting through wiring diagrams) and it's all in and running great! Thanks Jamie for the write up on the conversion, although it was pretty straight forward.

      Congrats-4.0

      Good Job on the swap. I have about decided to rebuild my 2.8 and run it as long as I can. I just do not know if it is worth the money. I would like to get some photos of the rig.

      You can really build a 2.8, I love 'em. Go with a Schnieder cam, a 1.21 motorcraft carb from a '77-'79 400 and Duraspark ignition. You'll REALLY love your 2.8 after that!

      We used a '91 4.0 from an Ex that was totalled after we had just put in a rebuilt only 5k miles before, the kid kit a horse at 2am. The trans is the old Toyo Koygo from the '84, it'll live for a while.

      the TK and Mitsu manuals seem to be more dependable then the later Mazda 5 speeds IMO.... cant wait to see this on the trails! My BII is getting caged right now/this spring... this is the biggest challenge I have taken on yet! There is also talk of a SAS between the wife and I...we will see how that goes ($$$$$)

      Yup the SAS is a bit of cash, we have a shop so it took a lot of the sting out. Would've liked to have gone with XJ long arms, but even now we've noticed that the front driveshaft bound on full drivers droop. We clearenced the yoke and it's been fine, but wouldn't take anymore flex. I wonder if the folks that are getting super flex from the front are looking at driveshaft bind. There is no cardan joint available for the BII front, the only fix would be using an EX trans with a very rare manual t-case and then the EX front driveshaft. More $$$.
