The housings are different, the one you have could be made to work but then you'll still need the axle shafts as the locker diff uses a longer spline on the locker engagement side. You might find that a wrecker won't want to pull the whole diff apart and even if they did your better off buying...
Terrain Tamer heavy duty rad by the looks? I rate those, that will never get hot, my 1VD never makes it past 93°c on the hottest of days with one of those.
The new ones still drive the same as the first coil front end models when they were new, some 25 years ago now. Few more interior comforts these days but more or less still essentially just a workhorse as it should be.
Lost personally with the introduction of the 4cyl and auto in most people...
If you like the wagon style honestly keep the 80. So much better than any 2000 or older 70 series. The 1fz is better than the 1hz unless your bouncing around a farm.
Might be unpopular here but rual/outback Australia has proven the 1vd. It's a very underrated engine, i personally know of 3 farm utes with 600,000+kms and they get purely abused other than been regularly serviced. The 1hdfte, 1hz (n/a) and 1kd are the only other engines that last out here.
Thanks mate, the outer section is 75x75x 4mm which is heavy wall but I want as much roll over protection as I can practically. Internal sections are 75x50x 2.5mm and I can still pick that up reasonably comfortably by myself. The rest of my tray is 2mm and 2.5mm for the side rails to give it more...
Well I can feel your pain, at least you've stuck at it when most others would have long since given up. Is there somebody with a mill or lathe nearby? Machine shop? Milling that solid spacer down is super easy with a mill or even a lathe.
Most say if your using all new parts the terrain tamer solid spacer works out to be a perfect length. If you've reused your crown wheel and pinion it could be making things harder than they need to be. Also make sure your bearings have a coat of diff oil on them..... will change the tolerances...
Degree of difficulty to make that work is going to be high (if you want a half reasonable result). Hzj75 sub from factory was 90L so it may not even fit. Either way I doubt many have tried it before so unfortunately information may be limited.
I'll chime in and say that your opinion on the cooling system is shared over here. I cannot get my 1vd hot, and I've pulled hills towing with the ambient air temperature north of 45°c and it just does not get hot. The narrow nose FTE 79s also had huge radiators that work extremely well.
