TD42 in a GU replacing a RD28

[sooty_10]

Pretty much what Kev said, plus you need to change brakes. It can be done but you would be better off finding a roll over gu td42 and swap everything over. If your still keen on the conversion.

Just curious why you say the brakes need changing?? They are exactly the same between GU models (except tb48)??.

I have done this conversion mate and as alluded to by Kev you will need to move the drivers side engine mount (or fabricate an offset plate), you will need a TD42 gearbox and crossmember, diffs can stay as they are but at 4.6:1 you will most likely need larger tyres or it will rev a bit on the highway, front tail shaft is the same, rear will need some flange changes either on diff end or T/case.

Extrimal mentioned the throttle cable also need swapping over. There are off course other little bits and pieces which need modifying or using TD42 stuff. I had a complete donor so just swapped bits as needed using everything from the TD42.
