Amdro original boot jump K9 modification

[Ciotog]

Hi guys, can I seek your advice on this… We have an Amdro original boot jump which we happily used many times in our B9 Peugeot Partner. We paid for the extra leg to be included, to support the fold-out bed frame when the rear seats are removed. We have since changed our car for a Rifter (K9), and discovered that the support leg for the fold out bed is too tall due to the way the rear seats fold flat in the Rifter. Amdro have a conversion kit with a different size support leg which they sell for just under £300 including replacement blinds. I was wondering if anyone had the measurements of the replacement parts in case I fancied giving it a go to make up myself? Thanks in advance!!
