1984 RRC drive flange

Hi all can you get drive flanges for a 1984 Range rover classic lots seem to be listed for newer after 1986 ones but can't seem to find any for before 1984, anyone with a part no ? Or am I missing something like they are supposed to be one piece half shaft and flanges Thanks all

Drive flanges for the transfer box output shaft flanges or the axle diff input shafts?

Which transfer box do you have?
If it's the LT230 transfer box output shaft flanges you need to look to see what you currently have fitted as there are more than one type & they aren't interchangeable.
You will find you'll either have a multi-splined one or a 4 splined one.
Mine's an '86 reg & has the 4 splined ones on the transfer box.
But bear in mine these are big boys meccano kits.
Just disconnect the prop, remove the big centre nut & look.

Don't bother with cheapie pattern seals for these either. They don't work for long.
