Hi! I am from Romania and I am building my own Locost from scratch from the Haynes manual. My donor car is a Ford Sierra and I don't know if the Sierra uprights can be mounted with the standard wishbones that is described in the book. Can you please tell what should I modify?

Is it the Haynes Raodster bookby Chris Gibbs or the older Escort based RonChampion "Build yourself a sportscar for £250" Haynes book?

It is the older Escort based RonChampion "Build yourself a sportscar for £250" Haynes book

Then you'll have to alter them (and a fair few other bits).
If your donor is a Sierra it'd be a lot simpler to build to the other book design.

It might be, but it takes time for the book to arrive in Romania and that is why I asked here.

They "posts to worldwide":
It shouldn't take more than week...

Or - you can download pdf version and wait patiently for paper version...
