I have a lumbar repair kit fro standard 300 seats. Works perfectly. Kit consists of lumbar pad bracket to hold to frame adjuster knob and spacer. Pretty straight forward to fit can provide instructions.

So are they pretty easy to fit by Adams standards or would us mere mortals be able to do it too ?

I might have these as i like the standard seats but both lumbar bits are broken.

I might have another kit if you need one for both. Yeh the not too bad to do mate.

Well as no one else seems to have jumped at this amazing oportunity i'll have them. I'll PP you for them and the filter. How much P+P or all in?

*Edit just noticed that includes P+P
