Made some more progress today.
Body work is not finished but I did a fit up of the bumper and tail light to see if i had the body lines right. A little more work to do but pretty happy.
As far as I can tell the standard 850 rear bumper will not fit an AWD as the exhaust outlet is on the wrong side. (unless the standard 850 has cutouts on both sides... I am not sure). I have been looking at some 850's on the internet and found a couple with V70 XC rear bars fitted. I like the way it looks, have an XC rear bar and don't have an AWD rear bar so it looks like that is the way I will be going.
here is an example.
The XC rear bar is slightly deeper and looks good in conjunction with a R front bar. I have managed to source an R front bar, it needs a few repairs to some cracks on the lower corners but it should come up quite nice.
I have also fitted V70 rear lights because the clear indicators look much better.
Rear spoiler is also fitted although it will need painting as it is currently silver, I will get the rest of the body work done, including the front bumper repair and then get front and rear bars, rear 1/4, tailgate and rear spoiler all repainted, the rest of the car looks quite ok, so will probably leave it alone.
The front seat that I thought I had sourced turned out to be a dud so I am on the lookout again. Will update my list next. I would really like some 850R seats but so would everyone so I don't like my chances.
some pictures.
