thanks for the advice on the polybush fitting. I did take out the metal sleeves Ian, not sure it would be possible to push them in while they were still in place. Job is done now and was quite straightforward (looking back)
I'll get the latest wildlife invasion out of the way

these buggers are called "Rain Moths" or
Trictena atripalpis
http://www-staff.it.uts.edu.au/~don/lar ... ripal.html

they grow quite large, have massive bodies and defy the laws of physics in being able to fly at all.

mostly they don't fly, they kamikaze out of the sky and belt into things, particularly cars driving on the road.

they come out in huge numbers, after rain.

they only seem to last overnight, then die, creating a huge mess around outside lights, or get into gutters and stuff up the rainwater we collect. Anywho, not poisonous or anything, but they put a stop to spray painting at this time of the year

slight setback, I've picked up the headlining but I've got to say it ain't what I'd hoped for. The guy who made it is a good craftsman, the workmanship is great, but unfortunately his selection of the material is nothing like the original. He has used a bone coloured vinyl (thin) and it has very little texture (you can't see any really). I'm sure it will fit up okay, but I'm not sure it will look decent. His instructions were to make up a new one in a similar material and I'd trusted his judgement in what a similar material would be. This puts me in a really bad position, since there is still a stranglehold on funds and this new headlining wasn't exactly cheap. Buying a new one out of better material is but a dream.
so, do I or don't I fit it and hope for the best ? It'll look okay and be smart.
do I try and find some better material and have a go making it myself, as per the original plan ?
would I be happy looking at the roof everytime I drove the car and knowing it is very different.

The trimmer did suggest using carpet underlay for the roof sound insulation. Bond the unsealed surface to the underside of the roof using contact adhesive, leaving the sealed (thin plastic) side down. It sounds like a plan to me. Has to be better than plastic bags flapping around in the roof above the headlining. Again, your thoughts would be appreciated.
Finally, I bought some material for the rear engine bay bulkhead, sound and thermal insulation, in black, but the surface isn't exactly rugged, like the old stuff which has that think rubber-like layer over the foam. Kind of stuck here, I suspect I need more rugged material. I can use the new stuff inside the car, around the front footwells, but think I'll have to keep on searching for engine bay stuff.
should be able to get the rear axle painted today (in daytime, the moths, "they mainly come out at night"

), weld up the old rear shock absorber mounting plates and clean and fit everything back up.
