After 2 years of research...
Well,
Been doing the research for the past 2 years and this is what I have found:
1. It is quite easy to do, and the set-up should be enought for a healthy Rover drivetrain (engine) to sustain with 37" tires. The issue is that you have to collect some parts that must be sourced from different suppliers/countries...even continents
2. You can run the Toyota R&P that is a hypoid design, that, by design are stronger than the Rover design, despite the exact same 8" size.
3. You need to bore out the front bearing/spindle and the rear if you want to run the 1.31" axles.
4. Speaking of which, the Dana 60 (non-HD) comes with the same sized axles you will with this set-up (1.31" x 30 splines).
5. All sort of lockers, LSDs, Spools are available
6. You can use the Longfielded CVs (
www.longfieldaxles.com) for 125-145$ each that are currently surviving 35-39" tires, depending on all the other variables.
7. Costs (so far on me in Lebanon without shipping is):
a. R&P 4.88 @ 160$ each (US)
b. Dual ARBs @ 650$ each (US)
c. Rear Axles @ 450$ pair (Aust)
d. Front Axles @ 450$ pair (Aust)
e. CVs @ 145$ each (US)
f. Front & Rear Flanges @ 60$ each (Aust)
g. Toyota 3rd member cases 2nd hand @ 100$ each (KSA)
h. Re-bored fron Spindles @ 60$ each (Aust)
i. ARB Pump @ 190$ (US)
TOTAL: 3,560 (NO SHIPPING COSTS)
Compared to any other set-uo that will NOT hold up to 35s will sum up to 4870 (1500 front CV kit, 800 4.11s, 1300 ARBs, 120 each / flange, 190 ARB pump, 600 rear axles), and, WHEN (not "if") you break something, its gonna cost you A LOT.
Since I have to import stuff ANYWAYS, and toy 3rd members are cheap around here, that is why I have decided to go for the BEST set-up possible wilst keeping the Rover axle casing for the best clearance.
All this should be in teh Truck by End July, so will make sure I'll give you some feedback.
