+ driveshafts,and depending on engine he has now,probably gearshift linkage and clutch slave cylinder with hydraulic line...if he has a/c and wants to keep it he needs lower a/c pipe...he needs complete donor car.

2.8 vr6 out of golf mk4 would be the best option,but it's the easyest to find a complete golf and swap everything out of it in your car.

I'm speaking about shaft that is going to the diff(input shaft-connected to the engine,output shaft connected to the diff),not the driveshaft...in the parts catalog it's listed as output shaft.

original gearbox was DUU which has 4,25:1 final drive ratio and 0.85:1 5th gear ratio... speedo is now reading 10km/h lower than actual gps speed up to 100km/h and 15km/h lower above 100km/h.with old box it was reading 10km/h more than actual gps speed up to 100km/h but i'm not sure about reading above 100km/h,was it 10 or 15 km/h more...

yes,but output shaft is rotating 3-4 times faster than diferential...

original gearbox was rod-operated 5 speed 02K gearbox,now it's cable-operated 5 speed 02J gearbox. difference is that 02K is reading speed from gearbox output shaft and 02J is reading speed from differential.

195/65-15 winter tires,no difference on 205/55-16 summer ones as they both have similar diameter

'98 Octavia 1.6 glx,74kw,swaped original gearbox with '03 1.8t gearbox,now my speedometer is reading 20km/h lower than before(10km/h lower than actual gps speed,with original box reading was 10km/h more than gps).vag-com cluster coding didn't change anything.is anyone here familiar with eeprom editing?seems that's the only option left...i got my cluster eeprom out with vag eeprom programer,cluster is 1u1 919 034 j
