18mm anti-roll bar?

[angel]

While doing some front end repair work on a 1974 R4 today, I noticed that it had been fitted with an 18mm anti-roll bar up front.
Could it be from an R6 or what? The "poor road" R4 anti-roll bar is only 16mm diameter.

hi angel
did it have a small downwards dipped section as it could be R5 Alpine/gordini or turbo
have got one on my yellow peril will check diameter later as i am currently using it daily because of all our lovely english sunshine at the moment

hows your plein air doing ? i am sure it will end up looking nicer than some of the dodgy looking replicas that have been listed on e bay uk recently

edit update mine is 17mm cant rememember what it was off but pretty sure it was atmo 5 gordini (alpine in rest of world)or maybe 5ts/tx??
downwards kinked section is to clear floor change gear linkage

I remember vaguely the kinked R5 anti-roll bar and it is not like this!! Just like an extra thick R4 one.
