No they can not. I made the mistake of buying some but they are completely different from MK4's so don't waste your time.
No they fit different, although mk2 and mk3 and some mk4 polo gearboxes will fit. You want an 8P gearbox.
No they do not. The Mk3 uses an entirely different headlamp as compared to the Mk4. They will only fit if you swap the front end of your Mk3 with a Mk3.5 Cabriolet. Furthermore, Hella Makes Headlamp units that look very similar to the mk4 headlamps.
yes they will
Nope
yes as long as they are the same stud fitment. The mk4 golf is 5x100 bolt pattern and the mk3 golf is 4x100. unless it's a vr6 model which has the 5x100 bolt pattern so in general the mk4 wheels will not fit a mk 3.
IT SHOULD BE A STRAIGHT SWAP PROVIDING 98 GOLF IS A MK3.
Yes
Yes, I have it done on mine. The MK3 2.0 gearbox fails when it gets to high mileage. The Mk2 1.8 gearbox is bulletproof.
Yes, the gearbox from a 1.8 Golf Mk3 can fit a Golf GTI Mk3 with a 2.0 engine, as both vehicles share a similar platform and drivetrain components. However, it's essential to verify compatibility regarding specific model years and any modifications that may be needed for proper installation. Additionally, consider the gear ratios, as they may differ between the two models, potentially affecting performance.
You need to modify the mk4 steering wheel to fit. Get the 3.5 cabrio wheel. It looks similar and no mods required
No, the floor pans are completely different. The MK3.5 will fit the MK4.
the ceiling wouldn't fit because it would be a little too big, if you meant the actual glass sunroof it will definitely fit any mk3 model including jetta/golf/gti for sure.
