Thanks folks

My local small bolt shop has 'em. Bit far for you to come but.

Well, I've shelled out and bought a GKN, greaseable front propshaft. No 'lift issues' :-)

It depends a lot of where was the 2" lift(springs or whatnot) sourced from.

in my case, the 2" lift I removed from the D2 was replaced by a 2" lift from LRA.
I dunno what brand of springs and shocks the old lift kit were, they were all yellow. I can't remember any branding.

But with front of car lifted by chassis and front wheels hanging in the air, I had no trouble with front prop binding, or touching anywhere.

I installed LRA supplied springs and shocks(old shocks were totally gone and old yellow springs had sagged a bit relative to each other).

With new LRA supplied suspension, I couldn't get tyres in the air now, with the same jack setup.
My jacking setup is two airbag jacks and off cuts of sleeper timber to raise the start point of the jack.

ie. the LRA setup had just a smidge more static height sitting on the ground, but a heap more down travel than the old yellow setup had.
I found that brake lines were then stressed(got longer ones fitted) and also ABS lines had to be readjusted too. What I wasn't expecting was that prop then rested onto front cross member one full travel was reached.

ARRGGHHH!.

LRA sells a cross member drop kit(two types). Of course being cheap I went with the cheaper kit Never got the chance to fit it yet. The cheaper kit consists of two flat steel 'flanges' that get added to the cross member.

And to be sure the prop wasn't stressed in extension at full drop, I removed it from front diff to see how much more extension it had too. That is, be sure that the sliding sleeve wasn't topping out at full drop. I had a few mills of more travel.

Haven't done any off roading since suspension had been replaced, and in normal road use it looks fine, it's only going to be a problem when it flexes fully. Will get onto it in a few months to fully sort it, and undo my cheapo-ness and get the more expensive cross member drop kit, which doesn't just drop it, it rotates it by a few degrees as well, so overall less drop(more clearance) and clears the front prop.

But my front prop is just a normal type, just rebuilt all the joints, to be sure

I'm sus on that front X member. Mines in the bin (half the welded nuts were missing anyway)

I really don't see how that cross member could be doing anything structural with those tiny bolts holding the crossmember to the chassis, not to mention the light weight chassis brackets it's attached to.

I reckon it's there just to catch the front prop when it fails, kinda to stop the D2 from doing a Hollywood style pole-vault stunt.
