Hello all, i recently picked up a range rover 200tdi factory original, been standing 2 years, its a 1993, needs some tlc, but everything works, and every little part is on it, and its started so easy, and clean, has 184000 miles, thing is,i got under it and noticed the front prop was missing, i bought it without seeing first, didnt have time. anyway can anyone tell me which is the right prop to buy for it, nothing on the web, makes it very clear, a friend gave me one from a 92 petrol se, would that be the same, as the the one that should be on it, length is the same, from the flange to flange, also while im here, if you grab the flange on the rear diff, vehicle on ground, prop off, ive got about 2inches of knocking free play (backlash is it)?, is that too much?? and can it be adjusted, or should i just get another diff, thanks in advance for advice.
