Adam001 Posted March 8, 2020 Share Posted March 8, 2020 Howdo. So my defender has had a R380 in for a little while (m52 now m57 engine). Mine was a 19J originally so I have the LT230 on the bolt on mounts. Currently I have the lt77 tunnel fitted but I'm not happy with the fit on the LHS as I have a cooler fitted and I need more clearance. Question is, if i swap to the r380 tunnel will the shifter hole line up? Adam Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted March 8, 2020 Share Posted March 8, 2020 I think the hole will line up but the tunnels are different so you would need to change the seat box as well as there’s a bulge (for want of a better word ) on the drivers side, if you want I can take some pics for you tomorrow off my project as there’s no carpet fitted yet and could take some measurements for you as well .

Adam001 Posted March 8, 2020 Author Share Posted March 8, 2020 That would be ace if you could! Yeah figured I would need to swap the seatbox/bulkhead flanges too, I need to do a whole body realignment soon, so this will be the easy bit hopefully 😅 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted March 8, 2020 Share Posted March 8, 2020 I’ll take some for you tomorrow when I come back from work , I know YRM do all the individual seat box parts and I think they’ve started doing the front panel with the flange on for the seat box which would save you some cash if I’m rite. How’s the swap coming along? I use my 110 200tdi as a daily driver and you’ve got me seriously considering swapping it to a m57 engine , I might have a few questions for you later on 😁.

ianmayco68 Posted March 9, 2020 Share Posted March 9, 2020 Are these any good light wasn't very good tonight due to the weather , 1st measurement is from bulkhead to front of opening , second to back of hole . I can get some more if you need any . Quote Link to comment Share on other sites More sharing options...
Sigi_H Posted March 10, 2020 Share Posted March 10, 2020 (edited) I recommend to cut the tunnel in a left and right half. The halfes are easy to connect with a H-profile and it is a lot easier the to get one half ie for a gearbox oil change out, without scratching everything. I did it on my lhd.

Adam001 Posted March 10, 2020 Author Share Posted March 10, 2020 That's Brill thank you! Will get mine measured up and will post back for others Quote Link to comment Share on other sites More sharing options...
Adam001 Posted March 25, 2020 Author Share Posted March 25, 2020 So the LT77 tunnel is definately different to the R380. The gearstick hole sits approximately 20mm further back than the r380 version. Which makes sense as I believe the r380 sits around 20mm further forward. In this instance I cant swap to the r380 casing as it will clash with the differential lock lever. Doh, custom fabrication for me then!! Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted March 25, 2020 Share Posted March 25, 2020 Is a v8 tunnel different to a LT77 ? Quote Link to comment Share on other sites More sharing options...
Adam001 Posted March 25, 2020 Author Share Posted March 25, 2020 No idea actually, don't know if the lt85 had a different tunnel or if it just used one or the another Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 25, 2020 Share Posted March 25, 2020 LT77, LT85, LT95 and R380 tunnels are all different. Quote Link to comment Share on other sites More sharing options...
MonLand Posted June 30, 2022 Share Posted June 30, 2022 Not sure if this is against policy of this forum, but Robert spent the time describing the different tunnels here: https://www.defendersource.com/threads/transmission-tunnels-clarified.166075/ Quote Link to comment Share on other sites More sharing options...
