From memory, i think the gearbox mounts are part of the removable cross member on a disco so the easiest thing to do would be to bolt the discos crossmember on to your chassis.....it should fit. Doing iit this way would mean cutting the seat box about a bit as the bell housing is longer on a disco so the gear levers would sit further back. This isn't as abd as it sounds as you can quite easily graft the disco centre console in to the 110 to create a neat look, or fabricate your own transmission tunnel.
Someone will be along shortly to either confirm I am right or correct me! |

Jim is correct. I have just done this conversion on a 1983 110. However I bought a new galvanised chassis with the 300 tdi engine mounts in the right place. If you are doing the conversion on your own chassis you will need to remove the old engine mounts and weld in new ones for the 300 (there is another solution but it is very contrived!)
You will need either to source correct gearbox mounts and central cross member from a 300 tdi defender or you can do what I did and modify the Disco one which involves cutting and welding to make it deeper to account for the different thickness of the chassis rails. The 3 triangular mounting holes though are in the same place on all models so are you basic reference point. Make sure you keep all the plumbing for the radiator, intercooler, oil cooler etc from the disco and all the wiring for the heater plugs and the rest of the engine. You need to cut the radiator mounts down by and inch to bring the disco radiator frame low enough to get the bonnet slam panel on. You need the front prop off the Disco and will need to source a new prop shaft for the rear axle. Inside is the biggest issue and you will have to heavily modify the transmission tunnel. This is a bit of a pain to get it to look halfways tidy. My recommendation would be to throw out the existing tunnel which is only really like it is to get a middle seat in and to build your own custom tunnel which wil be wider and higher but allow you to use the discovery gear levers in the new position. I actually ended up extending and bending mine to get them in a nicer position (but then I also removed my seatbox and made a flat floor and moved my seats back a couple of inches to improve cockpit comfort. There is a photo story of my build if you are interested http://forums.lr4x4.com/index.php?showtopic=79226&hl= If photos don't show detail then just pm me, I may have better shots of specifics.

hi Mark
thank you very much for all that information. I think the link you posted is broken or not all there! Being ex MoD, the chassis is good but the bodywork is squaddyfied with plenty of little dings and the transmission tunnel has already been 'looked at'! the doors are an interesting fit too! They close and stay closed but the view through the gap is interesting;-) Do you know if it being LHD will throw up any problems, the handbrake for instance? Cheers Ian |

As said, the 300 crossmember is a bolt in job, BUT you'll need the 300 floor plates and transmission tunnel to fit it in (same as Td5 ones), although this does keep it nice and neat.
PM me your email, i've got pictures with all the dimensions on for the 300 engine mounts in a defender, I'll fling them over. LHD should make no difference. |
