Fitting a Citroën Xantia rear suspension cylinder to BX.
Xantia rear suspension cylinder to the left, BX one to the right. All other dimensions match, but the supply pipe union is somewhat thicker in the Xantia version, making it difficult to fit it in BX.
The cylinder is fitted to the carriage, the hydraulic pipe hole is protected with a M8 bolt against contamination..
..and the union is machined to 15,7 mm outer dimension in order to match the BX one.
