    As has been said, if you are looking at the Stage 1 V8 then this is a permanent 4WD with a centre diff. You have the choice of running in front or rear wheel drive by simply removing one of the drive shafts but unless you have it locked permanently or welded up the centre diff will seize fairly quickly. Obviously the requirement to lock the diff or weld it is because once one of the drive shafts is removed all the power will exit from where it was attached.

    Your other alternative is to install a gearbox from another vehicle that does not have a transfer case. You didn't say you wanted to keep 4WD (unless I missed that in a subsequent post).

    It does seem a lot of work to achieve something that many utes and trucks have always had, 2WD. Or have I missed something.

    If, on the other hand, you want 4WD as optional, then there are plenty of gearboxes with selectable 4WD but unless the ground you are covering is very soft then you can expect the transfer case to bind up, and quickly. What about locking hubs? Would that help?

    Well Ho assume no more...

    It wasn't a Suitable answer....it was a smartass comment.

    And about trying to be smart again in your last post... Do i need to tell you again... I hope not... you already took offence 1st time.

    Go play on another thread.... Although MOST are into Standard, or the old 2inch and muddies, some are not. I don't get on here sstiring up people looking for a EX Military, or someone wnating to know something I am not INTERESTED IN.

    Surely with all YOUR experience you would Surely no that being a Smart alect will create a Reply??

    By me asking Politely and informing it may be a dumb question, Which to NOW I know the answer(thanks people who helped) why put your smartass 2 cents in, then get upset about it?

    And about my lack of posts, I don't see then need to INTERFERE with peoples Threads/forums unless I can help or have an input..

    I actually have been a member here for a FEW years, if you would like to reasearch that too?

    Hi Chad,

    I think Blackknight had something to do with the Army drag land rover, he might have an idea about a front axle.

    I take it you already have the donor vehicle. I would have thought you would scrap all the drive line and go the Chevy way, but I am sure the standard V8 can be mated to a 2wd gearbox.

    From the tyre choice I don't think you are worried about 4wd. I did see a 4 door 4runner on a 2wd Hilux chassis, It looked good. Maybe the Toyota or another Jap 1ton chassis can be adapted to get your body down low enough. Or would this go against all the engineering you have looked at thus far.

    Good luck with this and try to get some of the build up pictures in the project pages

    thanks Dan

    I was thinking along those lines but due to the RTA laws, has to be classed as a ICV (indepently constructed vehicle) and incurrs around 3-5k of engineers reports etc...

    So unfortuantely I have to work with what i have, hence the questions.

    I have decided for 1st attempt I am going to keep the tyres same diameter.

    i have purchased whit wall inserts for the 16s and also MOON hubcabs to give the Rat look too. After much reasearch and info, both here and on the net, I have worked out, I can get a sort of FAT, Skinny look, by running 235/85/16 fronts and 265/75/16 rears.

    I will be painting the car cottage geen, and brushed over matt type original olive drab for Rat look.

    Also have been playing with springs etc...

    And have turned them Upside down to test height and clearance. There was a bump stop of about 3 inches that is now about 10mm, and only leaving enoguh clearance to not bounce or bump to be unsafe. So efffectively I have lowered around 6 inches, which may not sound like much, but think of how much a 2inch lift looks, let alone a 6 inch lift, except mines the other way.

    The sill type peice below the dorr and cab, has been removed, and I going to make one alot wider (height) to cover chassis, and will be like 4 inches from ground, so really gives an optical illusion of being REAL LOW.

    Not sure if i will do anything to the front, as don't want a POXY spoiler look, but if needed i wil have to make something to lower it too.

    Might have a play with the alloy welder and see if i can come up with a wide kind of bumper mimiking the original, would ideally rather no bumper though.

    i am making a narrow tray, steel box section with timber floor, that only just covers the width oc chassis, almost sitting on chassis, with 2 large steel Mudguard type guards(like hot rod) sticking out the sides covering the tyres.

    Gas tank will be directly, behind cab, sitting low on chassis and not sure about the cover as one third to half will be sitting up through tray. Thinking of 44 gallon drum sideways cut to suit, painted up.

    have led old scholl ford taillights round.

    Front lights fit in same original hole, but are us design tri spoke, with a green centre dot, and incorporating indicator in bottom quarter of the actaul light. i will fill in the holes where original parkers/indicators are and chrome the headlight surround.

    Thats where im at so far...

    Chad.

    Will still be the next stage.

    Just waiting to see if the rims can NOW be drilled to the 5/6.5PCD.

    Was only 1 load rated wheel, that could be engineered, and now may not have AUST Standard,

    Is being sold by reputable Wheel/tyre place, TYREPOWER so hopefully can be used.

    Specification is Load rated, but now AUST Standard don't seem to match up.

    Anyway, always a way around these problems, but I won't build something for the Public roads, that isn't safe for Myself or others, thats why I race the other Landy, can do it Safely.

    265/75s are 0.5" smaller in diameter than 235/85s.

    You could always run 285/75s at the rear...

    Hey mate i have the specs in front of me?

    Not sure if they are wrong.

    Is from tyre manufacturer, States 235/85/16 Diameter 807mm

    265/75/16 Diameter 802mm

    285/75/16 Diameter 830mm

    I didn't think the 5mm would worry me?


    or Calculating it...


    235 x .85 = 199.75
    199.75 x 2 = 399.5
    399.5 + 406.4 = 805.9mm


    265 x .75 = 198.75
    198.75 x 2 = 397.5
    397.5 + 406.4 = 803.9mm


    Maybe some tyre brands are different?

    I hope these ones i am buying are correct in their calculations.

    I could be wrong, let me know.

    Thanks Chad

    What you have to understand is that centre diffs work every time you go around a corner anyway so a few % won't wreck it overnight. Now if you were touring Oz in this thing I would say no but this is a toy and you will probably be fine with it until you break something else from youthful exhuberance.
