me too...well almost...300tdi manual box in to a 110Just done this exact conversion . 300tdi auto into defender 1985
hmmm debatableenngine sits as it does in discovery so no need to extend pipes.
cheap option...cut it upfor best job get defender 300tdi seat box and tunnel although you can hack and get old ones to fit.
do that when its out!!!! I didnt and it was a bas///d. Also change the handbrake linkage. I didnt...used the disco hanbrake...redrilled the back plate to turn it 90 degrees so disco cable reaches defender lever.change speedo housing from back of old box as auto is electronic.
arghhh £££££...easier to mount the engine/box to match the propshafts and extend the hoses.....or dont extend them keep the rad near the engine to allow 3" of space for large intercoolerI had to get my front prop shortened by 2" and rear prop extended by 2" as neither disco or landy prop fitted .
not mine...fitted perfectly. roughly 6 inches back from the 110 crossmember. Tried the gearbox/trans first with the 110 (petrol/lt77) transfer box mounts but that makes the gear/trans box sit too far the the left so engine sits at an angle. abandoned that plan and used the disco crossmember and it sits straight, had to drill a couple of holes each side of the crossmember for the 3 long bolt that go through the chassis. 1 fitted the 2 needed new holesuse the disco cross member need to cut a bit out as its to wide to fit between chassis.
