HI,
This photo is of my S3 FFR back in 1990 when I first bought it off the auctions, the rear cross member was OD and the Jerry can holders OD.
I've since re painted it and left the rear cross member black and jerry cans black
My helicopter lifts never had white stripes, (all three of them)
Can't help with heater, I actually pulled it out, they hardly worked when new, my 300TDI the heater hardly works but finally my Puma the heater works too well! so only took them 60 years to get the heaters working!
pretty common for a drag chain to be rapped around the bumper to pull or be pulled and bend the back side in/down
Hope this helps
Scott
