    You would only need the box especially if you want to stay cable clutch. Tommy made a good point there.

    I hve an 02a gearshift and cables if you need one. And a Rear box mount.
    The tower should come with the box as they aren't in demand. I'd recommend rebuilding the tower as my old one was quite loose compared to another one i found.

    Cool. I think it would be a good idea to go with the 02a setup. Ratio's seem spot on, and im sure it shouldn't be hard to find all the parts.

    I think the seat cable is best bet. Mk3 has hydro clutch remember :thumbup:

    The starter needs to match the box (as a rule)
    02A and 02J boxes differ in a couple of area's
    Most people tell the difference is in the gearbox end shifter tower (not the gear stick end) this DOES make a difference.
    The other difference is the drive shaft flanges,some are "push in" and others are "bolt in" HOWEVER! both boxes have both!!!!
    CDA is bolt in flange (ala 02J if you ever want an LSD)
    Some early 02J have push in flanges and early 02A style shifter mechs.
    in other ways,its a right minefield out there so its best to check here 1st before parting with cash IMHO.

    Cheers for the offer Collo. :thumbup:

    I think im going to go for the 02a conversion now and the ratios seem spot on, plus i think it will be easier.

    Thanks though mate.

    I think it's worth getting whatever gearbox you put in rebuilt for peace of mind and ensured longevity, all the more so if you're considering a LSD?

    From that point of view it doesn't matter that 02A boxes are older and more likely to be abused.

    On 02J boxes is it only the reverse light switch that stops you using the Seat cable clutch setup? I thought there was something about the box casing itself that meant the bracket didn't fit.

    Rich if you're having trouble sourcing the cable clutch parts try TSR they used to advertise the hydro>cable conversion on their website but that might not mean they can't still get the parts.

    No, everything else is bolt on. I have one in mine. The only bracket that isn't used is the extra bracket that mounts on to the chassis leg in the Mk4.

    Mind you, if it's a road car, you probably want the reverse light, in which case the 02A is probably easier. Not much in it really.

    I put the 02J tower in my 02A so still no reverse light... :(

    Got a manual switch wired in so at least I can see while backing up at night. Minor inconvenience I suppose for a wonderful shift.

    I haven't even wired one in yet! It's not an MOT requirement.

    If you go hydro clutch then you can use standard mk4 reverse switch. If you use a cable clutch the bracket gets in the way so you have to think of something else.
    I would go cable, hydro is nice but it was be a pain to fit. Lucky mine came with it.

    Cheers for all the info everyone, its much appreciated :thumbup:

    After reading all the threads and taking everything into concideration, ive decided to go for the 02A conversion, simply because it seems like the easier conversion and should be easy to gather all the nessessary parts.

    Good point there mate :thumbup: It would be an idea to find a good condition box, or get it rebuilt for peace of mind.

    I'll get in touch with TSR and see what they say. Im sure they will be helpfull over the phone.

    Does anyone know anyone at TSR ?

    The club had a discount arrangement with them but every time I asked about it I never got a reply, you might have better luck if you just straight up asked over the phone, I only ever inquired about it over email. No idea if it was meant to be labour or parts only or both.

    Also, Mart's (HotGolf) rebuild prices are really quite reasonable, the biggest chore is getting the box to and from him. But Shiply should be able to sort you out with that. If I remember correctly the LSD fitting is free with rebuild. Sorry if I don't, Mart!

    Thanks for that :thumbup:

    Will give them a call during the week and see what they say. I'll also PM hotgolf and see what he can do.

    Cheers :thumbup:

    Just wondering, what would be the best flywheel and clutch setup when using an 02a on a 20vT ?

    Would a normal 1.8T clutch and flywheel fit ok ?

    Cheers Rich :thumbup:

    Rebuild is a great time to get fly lightened at the same time. That unfortunately isn't free with rebuild.
