    I have two splits running 68 ball joint beams with disk brakes.
    Rear irs using kit from Indian Automotive, bolt in kit so you can go back if wanted , Creative kit is cutting and welding in.
    Using an L bug gearbox.

    happy to be corrected but you could go straight axle with the type 3 stuff. I’m no mechanic so perhaps one of the wiser ones can chip in on using the the type 3 gear.

    hi reb,
    it basically comes down to how low do you wont to go in the car height an hows the budget.
    Nothing cheap on splitties an you want good safe braking (drum brakes are good if you keep adjusting them and radius the brake drums first) Pay once cry once as they say.
    Once you use disc brakes in your splitty you, ll be stoked.
    Theres no protection infront of you so you want to stop real quick if needed.
    Using a Swing axle setup you,ll get the lowest set height. Then Indian irs setup, then creative is higher again.
    With the 68 beam i,m using the Volksconversion drop spindles with his disc brake kit to suit.
    I could of welded in an adjuster plate to get the even height but the spindles give you a like smooth up down suspension movement with an still light steering for turning.
    I have the creative weld in irs end, i personally would just use the indian irs kit for ease of set up. They have a shock absorber bolt in kit to change the postion due to the new irs angle setup.
    You can add a brake booster kit to this later on if you dont weld in the booster plate on your 68 beam to support a disc brake setup if you fit one.
    If you use the indian automotive bolt in irs kit its adjustable for your tyre camber an ride height to even out the car with the front beam which you get done with your tyre alignment/balance..
    A late AH beetle gear box will have higher gear ratio,s . So I idle around in 3rd gear doing 60klm p/h an then to 4th at higher speeds. Im running a 1776 engine so the engine horse power likes the higher ratio box especially when going up hills over taking slow trucks.
    You can drop it back to 3rd an rev it out to 100 easily then into 4th to over take back to 110klm.
    As for 12 volt power.
    You just need the correct 12 volt light bulbs fitted, wipers should be 12 volt but you can tell if there not as they,ll go 100 miles an hour when turned on. You can fit a voltage regulator to sort that.
    So next is what engine are you using? A 1600 will get you going o.k. if your on a tight budget
    cheers chuck

    heres the link for the indian irs kit.
    https://www.indianautomotive.com.au...products/bolt-in-irs-kits?variant=15198979590
    heres the contact for the front beam brakes an spindles.
    You can speak to john an he,ll tune you in on what you can do with the front end
    https://www.volksconversions.com.au/

    To finish off the rear end you just need a 68/9 spring plates or adjustable one, kombi cv,s, and torsion bars ,cv, boots and donut rubbers an torsion covers /bolts and and beetle cv,s and beetle cv boots plus your new shockies to suit.
    for rear hubs you can use nearly all of later kombi setup which is cheaper an easier to find off amy 73 up kombi.
    Then use creative engineering drum conversion on them to keep your 205 wheel stud pattern for your stock splitty rims.
    Ive attached there link which shows a video on how to install it.
    https://creative-engineering.com/product/130-pcd-rear-drum-and-hub-to-fit-68-79-bay-hub/
    Then your engine an a late beetle gearbox.
    let us no what you think

    I,m running a light truck tyre with inner tubes fitted.
    The tyre size is 195R15 70? By hifly made in china.
    I like road clearance so have the higher stiffer side walls truck profile tyres.
    It makes the steering nice an light too!
    Every one should fit inner tubes for splitty rims as they dont have the outer lip on it to keep the tyre on if you get a flat a high speed , also mine had a small amount of pitting when i got them sand blasted so they would of had a slow air leak anyways.
    cheers

    And use later kombi running gear

    theres a few different boxes you can use, just depends on the gear ratios with 3rd an 4th gear setups for better fuel economy an lower reving of the engine at top speed.
    Most use a single side plate or AH gear box. Again depends on how low and budget, heres some info for you on different ones, used ones usually go for around $400 an a full rebuild $2500
