33.7mm x 2.6mm wall tube

[Bonzo]

I was sneakier than that !! .......... I got several 1.7m lengths from the off-cut bin

If memory serves me right, you'll need about 18 bush tubes ( 16 for the wishbones + 2 for the rear camber adjusters ) Each 35mm long, 1m would be plenty.

I believe there is a spare set of tubes in the workshop wich have been machined to the correct length

Was going to stick them on ebay but never got round to doing it
