BXProject

AFAIK BX rear struts are now NLA.
Xabty rears will go almost straight on bar a bit of choppy vhoppy of the union spigot.
Oh, and swopping the pushrods over..

I suspect as the years go on then yes, modifying shit from other, newer cars will be the only way to keep the BX going. I doubt it'll ever have the spares support of the 2CV or DS etc..
So it's modify or die I guess..
Since I just cant find a newer car I like I'll keep modding the BX..

See this is my quandry, all be it not much of a quandry.
"Since I just cant find a newer car I like"

I just can't imagine being in another daily car (other than an XM, or a C6 now I think of it). There a few modern cars I quite like the look of, but that's completely different from liking driving and owning it.

If I had the space and facilities, I'd run a small fleet of classics...
BX TZD
BX 16v
Triumph 2000
Morris 1000
Citroen DS
Citroen CX
Rover P6 V8

There, one for every day of the week, the TZD being the work horse of the lot

You've already got more than half that wish list though haven't you?

Indeed I have my bunny hopkins, although the Triumph needs a full, bare, down to the teeth rebuild and I haven't (yet) got the garage facilities to do it (+ I need a lot more skill & practice) but the Morris can be done on the driveway, one sill is all that is required structurally, but quite a bit of other mechanicals/brakes/windscreen rubbers etc etc. I want it to be original
