Tintop Roof Cross Braces

Hi
Does anyone know if its possible to buy the cross braces under the roof skin still?
Or if not, are the rear braces the same curve as the front ones?
Hoping to remove an 80's glass sunroof and weld in a patch and need to replace the one that was cut out.
Thanks

all different part numbers im afraid. the front one is 171817121A.

classic parts have them, but a little pricey

Thanks for that. Will get the front one ordered as its the only one thats been chopped for the glass sunroof.
 

I've got a roof panel chop (non-sunroof) from a 5 door that is looking for a home.  It was cut from the pillars so braces should still be intact… It's in Herne Bay, Kent so depends how close you are… £40 and it's yours

Anyone know the part number for the centre brace?
position 7 on picture
after a 4 week wait from classic parts I realised I ordered wrong one! Doh!

#7 is 1718171119, not available anywhere it seems
