front and rear arb sizes

[Sophia_Bush]

on the later flat arches that had the wishbone mounted arbs what size are they? also what size rear torsion bars and arb did they run?

From RPO (build) No.8331 which I'm fairly sure is the start of Mk2 shells. You'll find it on the sticker on the driver's A pillar (both of mine are 84** and they are "cross-overs". i.e Mk2 single plug)

Front ARB is 21mm. TBs are 17.9mm and rear ARB is 18mm

This is from Citroen's parts CD. I've checked 3 and 5 door, 1.1 petrol and 1.5D and they're all the same after that build No.

Hope that helps.
