Headlining questions.

[persiflage]

I’m now starting to look at completing the interior of the car (FHC Sprint) and have questions wrt headlining.
It’s a very long time since I dismantled the car and of course I didn’t identify the support tubes. Brian Buckland suggests in his book (page 137 upholstery) that the three support tubes are the same length but inspection shows that I have three different length measured along the outside curve. 108,106,105cm.
Any suggestions as which goes where?

I sorted mine by fitting to the car without the lining, then swap them about until they fit nicely and line up.

My first 2 are both just a bit less than 106 mm. The back one is the long one at 108 mm. '89 S4

'69 S4.

Thanks for that.
Played around with them today and the long one certainly fits better at the rear.
